Thanks, Jaime!
In doing some testing you suggested, I found that the issue was with a conflict with the W3 Cache plugin. As soon as that plugin was deactivated, Event Calendar functioned perfectly with no issues.
Figured I’d let you know, in case this may help with any future resolution between the two plugins. Would love to have both still active, so if you know of any solution or fix, please let me know.
Thanks again!
