I have not been using any of the club layouts or any other custom layouts, and I have never been a subscriber. The default layouts have always been running fine. I'm not quite sure which version I upgraded from, but I'm pretty sure it was a 1.x version (1.5.x?).
As far as cache goes, I have verified that all caching is disabled for my joomla site and in the JEvents component. Just to be sure, I cleared the joomla cache on the control panel.
My browser cache does not seem to be the problem either, as I have manually cleared it and tried navigating to the calendar on different devices as well (with same results).
What about uninstalling / reinstalling JEvents? Or will that drop my database as well? I'm really in the dark here..
If it helps, I can also send you a link to the page.
