Really strange. I've now tried with CB Auto Actions and the change of user group works fine (changed back to "No change of user group" in "Subscribers User access level settings" ), but it still "blocks" part the function of the CBSubs URL. The part in the PHP-script that calls the procedure in MySQL is not run (the part that changes username if not numeric to highest not used username). When I disable the CB Auto Action the PHP-script and the procedure works fine again. Looks like the server is "overloaded" with tasks and misses the procedure part. I tried with
sleep(2); in the PHP-script to delay the call of the procedure, but it doesn't help.
If I put the URL (
www.url.se/xxxx/xxxx/updateuser.php?user_id=10600
) that CBSubs URL uses into a browser the PHP-script and the procedure works fine.
I can't see any difference in the logs of a fail membership (username not changed) or a successful membership (username changed).
Fail
Successful
