Hi.. First, I want to tell you that the support here is awesome.. thank you everyone in advance.

I'm trying to setup a new event, but after enabling Online Registration and completing the required information I'm getting this error..

Fatal error: Class 'HTMLPurifier_AttrDef_URI' not found in /home/carams/public_html/sites/all/modules/civicrm/packages/IDS/vendors/htmlpurifier/HTMLPurifier/AttrTypes.php on line 29

I've tried different variations on setup like enabling multiple registration, enabling multiple registrations from same email.. etc.. but I'm still getting the same error, so I don't think it's related to setup of the event.

I've searched boards, googled it but I'm not finding a solution.

i deleted the folder template_c in /sites/default/files/civicrm/templates_c  but still getting the same error.

Thanks!
