Profile links invalid after plug-in updates

We recently updated several CB and CBSUBS plugins to their most recent version. After updating we can no long access profiles from the user list or from the edit profile link. Some links produce the message that the "Profile does not exist or is no longer available" or they produce a 500 system error.

This is a critical issues and we have exhausted our options in looking for a solution.

Please help...

Enable debug mode and maximum error reporting in Joomla global configuration then retry and see if any errors are output to give you a hint as to what is failing. Be sure you did not just update a few plugins, but ensure everything is up to date as long of plugins interact with one another.

Thanks for your response Kyle.

We have verified that all installed plug-ins are up to date. (Both CB and CBSUBS) This is a production site so I would like to get away from turning on the full debug mode as it is a heavy traffic site.

Have you seen this before? Are there any recommendations that we could investigate before resorting to the full debug mode?

Thanks,
Scott

Set the debug plugin within Extensions > Plugins to only be accessible to Super Users so regular users won't see debug output at the bottom. You can check server error log to see if any errors are present, but they likely were suppressed if error reporting was set to none or default. You really need to turn on debug mode and maximum error reporting to better see what's going on even if only for 1 page load then turn it off.

Have you seen this before?

Yes, it's either a memory issue or a fatal PHP/SQL error.

Are there any recommendations that we could investigate before resorting to the full debug mode?

Disable non-core plugins 1 by 1 within CB > Plugin Management to see if a plugin is causing it.
