Good morning. So this is what I did:
-Deactivated all plugins;
-Switched theme to 2016;
-Activated The Events Calendar and The Events Calendar Pro;
-Logged out of WP and cleared all browser cache, history, etc.
-Restarted browser and tried to log into WP and got the following error:
Fatal error: Call to undefined method Tribe__Settings_Manager::add() in /home1/littlik1/public_html/wp-content/plugins/the-events-calendar/common/src/Tribe/Main.php on line 237
When I reload the page, the WP Dashboard appears, but when I browsed to the WP Tools > Export page, I got another error:
URL: http://littletonrocks.com/wp-admin/export.php?download=true&content=all&cat=0&post_author=0&post_start_date=0&post_end_date=0&post_status=0&page_author=0&page_start_date=0&page_end_date=0&page_status=0&attachment_start_date=0&attachment_end_date=0&submit=Download+Export+File
When I deactivate The Events Calendar plugins, I don’t get any 500 errors.
Thank you for your time.
