Update, it also produces duplicate categories.

Hello Carl,

I can't produce the error in my local. Can you provide us your backend and FTP access so we can have a better look on your issue here?

Sure, I have included the site details.

Hello Carl,

Thanks for the access. I've tried to replicate the issue on your site by create and delete the group. The group is successfully deleted: http://screencast.com/t/IFnkdKphm . Did I missed anything?

sorry.... i meant group categories

Hello Carl,

May I know which Group Category that has this issue? I've tested it and the delete is working fine: http://screencast.com/t/t6tMRnMUI

It does not matter the name, create any category and then try to delete it and you will see the error. I have created this video to assist you.... https://www.youtube.com/watch?v=pNNjQWTC4js

Hey Carl,

I just tried to delete the group category and it works fine for me as you can see from my screen shot below.

If you want to replicate the error do it more than once. I put video in this thread so you can see and I just tested again and first time was ok, then the second time it gave duplicate categories and then gave the error I posted.

Hello Carl,

I've tried multiple times with different browsers to replicate the issue but still, I can't see the error.
