Hi Thomas,  that looks like a bit of an edge case with your cart config and PHP version.  I've applied a hot fix that addresses this.  Can you visit Backlight > Backlight Modules and click Reinstall next to the Cart Add-on? 
That should fix it, though you may need to try a different browser or clear the cookies for your Backlight site in your current browser if it doesn't appear to fix it immediately.

It could be that the contents of what we're putting into the sessions is different to that of BL1 and raising a false-positive for Imunify.
I asked about your ISP in case it was in an exception list that BL1 had.  We treated sessions differently for three ISPs in BL1 that raised errors when trying to save in data/sessions rather than the tmp folder.  Since then I've found the actual reason for them failing and coded around the functionality they provide rather than abandoning the use of data/sessions wholesale.

The session files are not malware, so your host should not be quarantining them.  Can you configure Imunify in your cPanel to ignore that directory?

We will not be changing this, for reasons that Daniel outlined.  The emails come 'from' your email address.  If you click reply to an email the reply will be addressed to your client.

Hi Michael, sorry to hear that your hosting issues have continued.
The installer has likely made changes to your database files.  The database upgrade should have made copies of the previous versions within each respective database_backups directory.  To copy the main three back, see whether you have the files to make these copies (all paths assume you are in the backlight/data directory):

publisher/database_backups/master_3_2_3.sq3 to publisher/master.sq3
designer/database_backups/master_1_2_3.sq3 to designer/master.sq3
admin/database_backups/master_1_2_3.sq3 to admin/master.sq3

I am not sure if keeping any -journal files around will cause issues (e.g. admin/master.sq3-journal).  Perhaps make a copy of these and delete them

It looks like a compatibility issue between the Okapi web module and cart with Backlight 2.  I have updated the file backlight/modules/module-cart/lib/js/jquery.ttgcart-backlight.js on your server with a fix and will update the Cart module with that.  There should be no need for further action on your part.

I've found a problem - the wrong index.php had been uploaded into backlight/installer/
Can you visit http://sweetlightgallery.com/backlight/installer/ and continue with the process?

Have you not run the installer yet?  That's part of the installation and upgrade process for Backlight 2.

Make sure that you've copied the correct .htaccess files into the correct locations.
The .htaccess file at the top of the extracted Installer zip needs to be uploaded to the top of your website (e.g. under public_html)
The .htaccess file located within backlight/ from extracted Installer zip needs to be uploaded into backlight/ on your server.

Hi Jon, who are you hosting with?  It could be an issue with the file submissions being more frequent than their network settings accept.

This is fixed in our testing version.  We hope to have it out in the next maintenance updates, by Tuesday.

This is a bug.  We'll look into it.  In the mean time, can you disable pagination for your search page?
