I recently upgraded to Event Calendar Pro 2.0.11 and the plugin appears to be causing a conflict on my site. I had the previous Pro version and my site was workingThe main menu in the header is a rollover function to display the submenus. They are currently displaying “flat”. The rollover pop-outs on the main monthly calendar page /events/ are also not working.
When you say you had the previous PRO version is that still the case? If you are using The Events Calendar 2.0.11 then you will also need to use Events Calendar PRO 2.0.11.
One other thing: can you review this thread? It’s relevant because your site is using an old version of jQuery (1.6.2) – that is causing some problems here.
