Events are displaying an error at the top of the page, even though Joomla Error reporting is set to none in Joomla.

The error reported is:

JUser: :_load: Unable to load user with ID: 305

Link to a page displaying the error: https://www.certifiedinfosec.com/events/event/48-iso-27001-cyber-security-certification/383-27001-training

I am running latest Joomla and Matukio Events.


I recently implemented open_basedir, so perhaps I need to know about a special path to include beyond what I already have there.
