Fatal error: Class 'EM_Tags' not found in ../classes/em-event.php on line 780

I’m getting this error as well. I’ve tried reinstalling EM 5.5.1 numerous times, both from the dashboard and via FTP. However, I’m finding that mine are NOT being duplicated.

Fatal error: Class ‘EM_Tags’ not found in /home/icrossro/public_html/wp-content/plugins/events-manager/classes/em-event.php on line 780

Hi, we’re aware of this issue and will fix asap in the next update.

Currently the fix is to enable event tags in Events > Settings > General > General Options

I simply commented the respective lines in em-event.php out.

the latest dev version should fix this by the way

Thanks for having given a temporary fix for this problem.

should be fixed in the latest EM dev version – To upgrade to the dev version see here – https://wp-events-plugin.com/documentation/upgrade-dev-version/
