We have used CB URL since 2010 to call a procedure in MySQL and it still works fine. Now we need to assign users of a plan to another user group than "Registered". That works fine with "Subscribers User access level settings". But when using "Subscribers User access level settings" the CB URL part doesn't work. If we go back to "No change of user group" the CB URL works fine again. Should it be possible to use both these functions at the same time?

Joomla: 4.3.4
CB: 2.8.1
CBSubs: 4.6.2+build.2023.08.28.17.18.16.905ab5925
PHP: 7.4.33
SQL: MySQLi 10.5.22-MariaDB-cll-lve

Sorry for being unclear. CBSubs URL calls a URL to run a php-script ( www.URL.se/xxxx/xxxx/updateuser.php?user_id=[user_id] ). The php-script calls a procedure in MySQL (it checks if username is numeric or not, if not it changes username to highest not used username). This works fine since 2010.

Now we need to assign users of a plan to another user group than "Registered". We use the function "Subscribers User access level settings" (see attached screenshot with red box). This works fine, but the CBSubs URL is then not run. If we go back to "No change of user group" the CBSubs URL works fine again. 

 

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).
