Howdy ccvbcalendar,
That is no good at all! Perhaps the update failed halfway through, maybe the file did not download proper. We should try redownloading the plugin ASAP.
Before you do anything I strongly recommend that you make a backup of WordPress, particularly your database. Once you are satisfied with your backup situation, go to WP Admin > Plugins > Installed plugins. Under The Events Calendar plugin click Deactivate, then Delete. Once deleted, reinstall it by going to WP Admin > Plugins > Add New. You can either search for The Events Calendar from this screen, or download it from here then click “Upload” in the Add New Plugins screen and upload that zip.
Does that fix things for you? If not, you might need to redownload one of the other plugins. Perhaps they are corrupted? Again go to WP Admin > Plugins > Installed plugins. Next to each Tribe plugin click Deactivate, then Delete. Once deleted, this guide will walk you through redownloading our premium plugins. Upload each of them to the Add New Plugins screen.
Did that all make sense? Can I assist you further? Please let me know. Cheers!
