When using The Events Calendar plugins, you may encounter an issue where the calendar view doesn’t change or you can’t paginate past the current month.
If you do see one of these issues occur, there may be a simple fix.
Testing for conflicts
The simple answer is that there may be a conflict occurring with another plugin that is causing this issue. Often, this happens with security plugins, like Wordfence, or with a firewall like Modsec Firewall.
The reason why this may occur is that security plugins tend to block the REST API. To see if this is what is causing the issue, go ahead and disable all security plugins and firewalls. You may need help from your hosting provider when it comes to any firewalls installed.
