It seems like two addons/modules have some issue or can it be related to WHMCS itself? Please can you suggest way to debug the cause?

[brian!]

you'll need to check both modules are compatible with your WHMCS version... as per your previous thread, pvre is v6 compatible (a little vague), and according to Marketplace, buycpanel is v6.3 compatible... though it doesn't mean it actually is, just that the developer has marked it as such.

thank you, it indeed seems to be Addon modules related, because it no longer appear when i deactivate Addon module.

 

instead this error appears in /admin/error_log:

PHP Notice: Undefined index: description in /home/myusernamehere/public_html/admin/configaddonmods.php on line 0

 

Any way to debug which Addon module .php file is responsible, on which line? I assume i can add error_reporting(E_ALL); line into all main module files that are called in most circumstances, any more simple way? The error appears rather rarely, not daily, and i see it twice in same second.
