Hi Barry,
I am having a similar issue, unfortunately that did not work. Please see http://www.jaxterror.com/events on a mobile device vs desktop for better understanding.
The Developers of “The Events Calendar” plugin through the forum sent me the download.
Hello,
Unfortunately no luck with disabling other plugins and using default theme. Therefore, I had decided to try a different workaround using eventbrite with the events calendar plugin and I actually had the same issue and the response I received was.
We have determined the error is caused on 32bit servers.
They sent me a new beta version that fixed the issue, but wanted to let you know in case you have others with these issues. Thank you!
