We've tried everything to track down the cause.

As part of this debugging process, I just need to know if these two apps use GET requests for API calls?

You could inspect in the browser dev tools (F12) Network tab and observe the dbtech ajax calls. I don't know the AJAX URLs are for the calls but I guess it will be obvious and you could easily identify it.

API calls are not performed using AJAX, they are performed using the {vb:data} template tag which is then resolved into a PHP function call during run-time.

Just installed on 5.2.4 and it was a clean install.

Tested each button and they record and display in the postbit as described.

The 5.2.4 instance was a clean install not an upgraded board database.

I have disabled notifications for 'likes' but i'm still getting pm's:

The setting only covers emails, at the time of creating this modification the Notifications interface for vB5 didn't exist.

At this time there's no way to disable those PMs.

Actually I wasn't getting notifications, I was only getting messages. I had to comment out the code that did that and reupload the product.

This was my favorite mod on VB4x...... does it work with 5.3?

All of the DbTech Mods have minor issues on vb5, but I continue to run this Mod and a couple others from them, on my 5.3.0 forum.
