Event not found error only on classes

@gnarly Issue solved. The cause of the error has been identified. In this case, it was not a direct problem with JEM.

We try to make JEM stable, a benchmark of event manager by Joomla, and useful for users. Each version adds new features to be more flexible and powerful.

One more thing:

You can hide past events without using the archive process by configuring the view menu with this option tab (see image).
With this setting, past events won't be displayed, and you'll only see events up to 60 days ahead, preventing the creation of numerous event pages.

Thank you for using JEM. If you can, we would appreciate it if you could share your opinion about JEM in the Joomla Extensions Directory: extensions.joomla.org/extension/jem/ Your feedback helps us improve JEM and assists other users in making informed decisions. JEM is a free event management component for Joomla, developed and maintained by an active community of volunteers.
