Hello Marina,
Thanks for writing in!
I checked the website and can see that you are using X Theme. Have you rolled back the changes from Pro Theme to X? In case you are converting from X to Pro on a staging server, please share website login details in secure note for us to take a closer look.
In the mean time, please try following solutions:
- Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
- Increase the PHP Memory Limit of your server. Click here for more detailed information and how to increase the PHP memory limit.
If you still have problems kindly get back to us with the result of the steps above and URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case.
Thank you.
