Twitter integration not working


Active member
Hi there, sorry, it's me again...

This time I'm trying to integrate Twitter to my new forum but I get this error:

Could not retrieve a valid Token response from Token URL:
<?xml version="1.0" encoding="UTF-8"?>
<error>This client application's callback url has been locked</error>

I have no idea...:(

2) Leave the checkbox checked and change the callback URL to match exactly the correct callback URL.

The exact correct URL to enter for this board would be:
