If the lightbox is disabled, the code looks like this,

"lightbox";i:0;s:16:"

but make a backup of the database before you change anything

Unfortunately that did not fix the problem. I turned off all plugins except the WPForo ones. I even switched to the standard 2024 theme just incase something with the theme was causing the problem. But no luck at all.

Is there an update I can make within the database table itself to switch the lightbox to disabled? I can see the lightbox setting within the "wpforo_attach_options" record in the main Options table. But I do not know what I need to change it to get this to work.

Here is the code around the lightbox, so it is more than just the lightbox.

"boxed";i:0;s:8:"lightbox";i:1;s:16:"download_via_php";i:0;}

Any settings in Advanced Attachments never get saved.

I think it's a conflict with another plugin or a JS minification by a plugin
Deactivate the plugins (except wpForo plugins) and try again.

I would like to disable the lightbox setting, but I have not found a way to do this in the front end. I click save, nothing happens. I even clear the WPForo cache and still nothing.

I would try again to make this change on the backend, but have not been about to figure it out in the wpforo_attach_options table. 

But now I want to change the setting that will allow users to delete their own attachments, but each time I try to save the settings. Nothing happens. 

Where can I find this setting in the backend database so I can hopefully change it?
