Hi altblackpool,
Thanks for your note. Am I correct that you are running Facebook Events with The Events Calendar, and without Events Calendar PRO?
We recently redid our license key functionality, and we’ve run into an issue where some folks are not able to put in their license keys if they don’t have PRO. The good news is that you can still use all the functionality of Facebook Events, as long as the plugin is installed and activated.
The only consequence of this issue is that when we release Facebook Events 3.6, you’ll need to update the plugin manually instead of automatically. We’re happy to assist with that when the time comes. And we’ll have the problem fixed in that version, so you’ll then be able to put in your license key and have automatic updates from there on.
Thanks for your understanding and patience while we get this fixed. Please let me know if you have any further questions.
Best,
Leah
