Hey Niko,
I’m sorry that The Events Calendar and Events Calendar Pro cause problems with the Avada Theme Fusion Page Builder! Page Builders are notoriously problematic pieces of software so I’m sure it’s the complexity of the builder code itself that isn’t playing nicely with The Events Calendar and Events Calendar Pro…
As for your question, no, deleting The Events Calendar or Events Calendar Pro will not delete events data from your site. As soon as you re-install these plugins and activate them again, the events data should all still be exactly where it was.
With that being said, you should make a back up of your site before deleting these plugins just to be 100% safe! If you don’t know how to back up a site, you can Google for some simple methods and there are many easy ways to do it. You can also use the WordPress “Export” tool to export all of the data for the following post types from The Events Calendar:
• Events
• Venues
• Organizers
Then, if you lose any data later on, you can just use the WordPress importer tool to import those XML files.
I hope all this information helps! You have a few different options and regardless of all of them, in general you should not lose any data here.
Cheers!
George
