Hello Lisa,
Thanks for asking.
I checked the website and can see that you are not working X Theme or Cornerstone. However, I can see Visual composer on the website. Can you please confirm as the issue falls outside the scope of support we can offer as you are not using any of our products.
In the meantime, please try out following solution:
- Ensure everything is up to date according to our version compatibility list here. Please follow the best practices when updating your theme and plugins. Click here for more information.
- Remove custom CSS and Javascript from the options or Child Theme and test the case.
- Reset your htaccess file by renaming it to
.htaccess-bak
. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button. - Increase the PHP Memory Limit of your server. Click here for more detailed information and how to increase the PHP memory limit.
Thanks.
