Hello Event Espresso Support, There are errors being generated when I update Event Espresso from Version 5.0.10.p to Version 5.0.18.p I reverted to a backup with version 5.0.10.p to clear the errors. Several Event Espresso plugins are active. [x] I tested for plugin and theme conflicts. In the errors I am seeing references to our preview URL,

Can you tell us your PHP version? and your WP version? Can you also update your plugin to latest version and see if you have any error. EE 5.0.19p should be available. thanks |

PHP 7.4.33 When I update to EE 5.0.19p there are PHP errors. |
Hi there, So out of those messages, the 2 that I can currently investigate are:
Those could be an issue within the message system, or they could be caused by the next issue:
The important part in that is Go to your accounts page HERE and look for Recurring Events Manager v1.0.0.p The other issues you mentioned in the admin are from the same issue. The PR version of the add-on is throwing a notice and then the other 2 warnings above “headers already sent” are happening because there is an error being thrown on the page an being output to the browser before a session is started. |
