Hey Brook,
Just got the site migrated over, however I am unable to add the license key to The Events Calendar plugin.
After reading through the documentation @ https://theeventscalendar.com/knowledgebase/finding-and-inputting-your-license-key/
I can see the problem is most likely because of different versions of the plugin. How do I update the version of The Events Calendar Pro to match version 4.2.4 of the core plugin?
Please let me know if you need any additional information.
Thanks!
