#1 Re: Backlight 3 Support » Unexpected error: Trying to access array offset on value of type null » Yesterday 10:58:26


Hi Mel, I'm not sure what is causing that.  Can you please email me a Backlight admin login, so that I can look into it?

#3 Re: Backlight 2 Support » Unable to access my Backlight galeries » 2020-05-20 09:40:51


Hi Mel, this is a Backlight 1 issue.  Your host is using a new version of PHP that is no longer compatible with our code.  Two options are to either downgrade the version of PHP in the control panel to 5.6.  If that's available that might work for the short term, but PHP 5.6 is no longer being supported.  The other option is to upgrade to Backlight 3.  We support up to 7.4 on Backlight 3 and will support any future releases of PHP in the next year.

#4 Re: Backlight 3 Support » Has anyone installed Backlight on AWS S3? » 2020-05-20 07:58:54


You're partly right on the need for FTP/SFTP.  That's at least needed to upload the installer files, or to upload custom stylesheets or PHPlugins files.  But it's not needed for the running of the site itself.  The Lightroom module publishes via HTTP, and the Backlight admin uses HTTP by virtue of it being web-based.  If I was in a position where I had to incur a high daily cost for FTP access, I would disable it after installing the site.

It sounds like FTPing through the load balancer was the culprit.  I use AWS a lot, including running load balancers that farm out work to multiple EC2 instances.  Our server admin access has always been directly to the respective EC2 instances via SSH or sftp, and not through the load balancer.  That requires each EC2 instance to either have their own public IP address, or to access with local IPs on a VPN (I haven't set up that VPN but instead use a service set up by real system admins, and not myself who is more of a developer.  So I don't know how viable that option is for a layman).

Something’s not right here. Backlight uses HTTP to upload images, not sftp (or FTP). I can’t find the pricing for opening up sftp on a load balancer. Can you point me to it?
What’s your business need for a load balancer? Were you running your site across multiple instances and if so was that because of high levels of traffic or other needs?
Which version of our products were you running?

#6 Re: Backlight 3 Support » Has anyone installed Backlight on AWS S3? » 2020-05-19 06:26:52


Backlight sites are not static, hence the requirement for PHP. It won’t run on S3 alone.

Can you elaborate on the cost associated with FTP. Some of TTG infrastructure runs on AWS, and I’m able to access it for updates using SFTP on an EC2 server without additional cost. The machine costs something like 5-7 USD a month in total.

Depending on the volume of photos and traffic, you could get away with a ‘tiny’ or ‘small’ instance.

#7 Re: Backlight 2 Support » Custom Thumbnails Sort Order » 2020-05-18 21:17:36


Hi Mike, thanks for the suggestion. The best approach for now is to set the cover image via the Backlight admin.
I have not heard that this is a widespread concern. Have you found the lack of ordering to be an issue?

#8 Re: Backlight 3 Support » This page isn’t working error page » 2020-05-16 23:24:09


Since we can't see your site and determine how your environment and setup have influenced things, there's no insight I can add.

#9 Re: Backlight 3 Customization » Redirect to homepage with hero » 2020-05-16 07:37:08


The area is not displayed when the cover image is not set in the album. Search results are a specialised type of album that don’t have a cover image set. I can’t see that change affecting embedded albums.

#10 Re: Backlight 3 Support » Backlight albums in Wordpress » 2020-05-16 07:19:35


I checked that the API call works: … lbum/55496
so that can be ruled out. One possibility is that the server or browser is unable to fetch from that URL.

#11 Re: Backlight 2 Support » Custom Thumbnails Sort Order » 2020-05-15 14:23:18


No nearer a solution. Have you considered setting the cover image using the Backlight admin instead? Let me know if that works for you.

#12 Re: Backlight 3 Customization » multi language support » 2020-05-14 10:26:29


I’ll be moving this into Backlight 3 Customisation

#13 Re: Backlight 3 Support » Update too 3.0.2 » 2020-05-14 08:15:35


That's great.  I will put in a proper fix in the next maintenance update.  FYI, your site was trying to load a module called backlight-3.  It should have been trying to download 'core' which covers all the core modules.  I've worked around this on the server, but will change Backlight itself to instead attempt to download the 'core' files.

#14 Re: Backlight 3 Support » Update to Backlight3 SUCCESS » 2020-05-14 08:13:53


That's great to hear! Thanks for letting us know.

#15 Re: Backlight 3 Support » This page isn’t working error page » 2020-05-13 21:45:38


/backlight/installer is only part of Backlight 2 and 3.  The installer files should be interchangeable.  For example, the installer that ships with Backlight 3 will install a Backlight 2 site if you haven't purchased Backlight 3.  We don't notify users of updates to the installer files,  as any changes are only minor improvements that aren't of general interest once you have a site up-and-running.

The installer files aren't redundant after installation is complete.  They also provides a way of making emergency recoveries should any of our updates through Backlight Modules break your admin in your environment.  If you visit /backlight/installer/ and go through the installation on a working site, it will replace all of the core files without resetting any settings.   I have not tested normal upgrades with the /backlight/installer directory removed, so can't guarantee that the site will function without it.

#16 Re: Backlight 3 Support » Update too 3.0.2 » 2020-05-13 21:35:34


I have put a workaround for this.  Either approach to upgrading should work now.

#17 Re: Backlight 3 Support » Update too 3.0.2 » 2020-05-13 20:53:22


Thanks, Mark.  I can see the problem on my test server and will work on a fix for this.  In the mean time, is there a button at the bottom of the page called "'Update All Modules"?  Can you try that and see whether it completes the upgrade?

#18 Re: Backlight 3 Support » Update too 3.0.2 » 2020-05-13 19:37:12


It looks like an edge case in matching order IDs and emails. Can you email me your order number and email used? Have you used another email with previous orders?

#19 Re: Backlight 3 Support » Website does not start, ERROR:Unable to find index page » 2020-05-13 18:47:31


I'm not sure how that would have come about.  Can you visit Designer > Pages, click on the name of the page you want to load on your home page.  Click Edit Properties and set Index Page to 'yes'.

#20 Re: Backlight 3 Support » Update too 3.0.2 » 2020-05-13 13:50:08


Hi Mark, I'm not sure what's going wrong.  I can see the error on the get-theturninggate server.  I'll need to dig further into this later today.  Is your site still functional?

#21 Re: Backlight 3 Support » double slash » 2020-05-11 20:27:39


Hi Nico, thanks for pointing that out. Assuming Backlight is actually immediately under the top of your site, then the double slash is nothing but a superfluous slash. I'll look into it.

#22 Re: Backlight 2 Support » Cart Function Changed Because of SSH Update? » 2020-05-11 06:12:34


Hi Don, can you provide a link to an album where Carr is no longer working?

#23 Re: Backlight 3 Support » Backlight 3 install OK but Lightroom Publish error » 2020-05-10 21:59:47


Hi Jan, his is another issue for your host to fix. When files are uploaded they are initially saved at a location configured by your host. It is that location or the permissions configured by your host that is causing the error. We have no control over this. All Publisher does is take those files and move them to a location within your website.

#24 Re: Backlight 3 Support » iframe or img error problems solved in BL3? » 2020-05-10 17:19:19


Hi Mike, we can let this one drop if you think it's working correctly.  The current version of LR Publisher is 5.0.1.  Please update it.  While the change from 4.* to 5.0.1 is not consequential from a functionality point of view, you need to use 5.0.1 in order to have the right fields presented in album editing.  4.* checks for Backlight 2 on the server whereas 5.* checks for either Backlight 2 or Backlight 3 in order to present the right fields.

#25 Re: Backlight 3 Support » Problem adding Watermark on Export from Lightroom » 2020-05-10 12:49:56


As the developer of the LR plugin, I think it’s a limitation in how our code works with the Lightroom SDK (software development kit). It’s been a long time since I looked into it so I’m not completely sure of the following cause. Lightroom’s publishing system wants to create one rendition per photo, and when it does it that way, the chain of other plugins get called. Our Publisher creates its own order of doing things so that we can generate multiple renditions per photo. That breaks the way that Lightroom would then interact with other plugins.
It was necessary to build it that way so that all the renditions of each photo could complete before moving to the next one. Otherwise we’d have the case where all the rendition types for all photos in the collection would need to be created before doing that again for each rendition type. That makes for a poor user experience as there would be a long delay before any photos started to be marked as published, and also creates issues if publishing stops for whatever reason. You could end up with the situation of all of your photos only having some of their renditions published.
