Just wanted to let our users that may be having issues with v5.0.2 know there is a new error reporting option that may be turned on in Administration->Globals->Logging item: User Debugging Options (log out then back in).
If you are having an issue, turn User Debug on. By doing so all PHP errors and most Window/Browser reported errors, will display to screen.
It was my hope that this feature will make reporting issues easier for those that may not have time or the experience to find where these types of errors are logged or reported. In all likelihood, anyone helping you to resolve your issue will ask for you to report these errors. Hopefully, this helps.
