Thanks for your reply
The theme I’m using is Divi, from the Elegant Themes
The plugins that I have are:
- Advanced Custom Fields
- Akismet
- Search Widget Category Wise
- Widgets display
- duplicate Post
- Managed WordPress Migration
- The Events Calendar Category Colors
- W3 Total Cache
It seems the problem is with W3 Total Cache. I uninstalled it and I could enable The Events Calendar
I’m having the same problem!
