Hi!
Thanks for taking the time to reach out to us with the problem you are facing. To better assist you I will need your help. Can you please confirm by upgrade if you performed an update of WordPress, The Events Calendar, and/or Pro?
Upgrades
If you updated WordPress I would make sure that you are currently using version 3.6.1 of our plugins which you can download from the “Account Central > Download” link on our site when logged in.
If you updated The Events Calendar but not Events Calendar Pro you will need to update it as we have dependencies between the versions.
Verify no other Conflicts
Once you confirm that WordPress and the plugins are up-to-date I would like you to confirm there are no conflicts from the theme or other plugins. This can be done by the following:
To see where the conflict is I would do the following.
- Switch your theme to 2010 or 2012.
- Deactivate all plugins
- Check if WordPress core widgets are displayed
- If they show re-enable The Events Calendar and add-on plugins
- Check if widgets screen still functions as expected, check if widget displays correctly in sidebar.
- If issue is resolved turn back on your theme and plugins until the issue re-appears this will tell you which plugin is having a conflict.
Please let me know once you have done the above and we can take next steps.
Thank you,
– Matthew
