I've inherited a Joomla site with an extensive portion built with Fabrik. For the most part it's been working just fine and I've been able to keep it updated, etc... However, since the Joomla & Fabrik 3.9 updates, we've had an issue adding new users via Fabrik form. In testing I've found that the form field validation doesn't seem to be working properly: some fields don't run validation at all, others fields fail validation when they shouldn't, etc... And if I try to submit/save the form, I get this error: 0 - An error has occurred. syntax error, unexpected 'regexp' (T_STRING) Return to Control Panel So far I've brought up a test non-production version of the site and updated Fabrik from Github, just updated to Joomla 3.9.1, etc... So far no change. Has anyone else had any issues with regex and/or form field validation with Joomla 3.9.x and Fabrik 3.9? Or have any ideas on what I can check on? Thanks!
