Event page only getting Error

Hi Team

I have error page in Event page in admin . Please find the screenshot. Event page error.
Remain all pages are working. find venue page also

hi, welcome in this forum where users try to help users. but help is only possible with enough infos about your system. it seems you have not the official joomla template.

We are using freeware template purity. its official and Free. Please check the admin panel issue of event page. Remain all page working fine in JEM

you can test yourself: if there is no problem with official joomla protostar and only official joomla plugins ( means with a clean joomla and JEM 2.2.3, then there's a interference between your template or plugins and JEM. It will be a problem of your template or plugin makers!
