Moodle 2.6 (previously 2.3.2)
When logging out of Moodle, all users are seeing "Coding error detected, it must be fixed by a programmer: PHP catchable fatal error". It still shows them as logged in and to click Continue. After clicking Continue, it logs them out. When I click the link to get more information about this error, I'm taken to the page that states:
"Coding errors (or coding_exceptions) are problems that are probably caused by incorrect code. For example a plugin that does not communicate correctly with Moodle core.
These errors are normally not caused by incorrect user input or temporary problems like the connection to the database server being down."
Below is the detailed debug message, and I attached an image of the message after I click Log Off. I don't know what it's looking for in order to fix it. No chat session was even used, but it's show in the Debug report.
