Could you please update to the latest versions?
Our latest versions are:
- X theme 7.0.4
- Cornerstone 4.0.4
This latest release contains fixes for several issues so be sure to check out the changelog (http://theme.co/changelog/).
After doing the updates, always remember to clear all caches (if you are using WP Rocket, WP SuperCache or W3 Total Cache) when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
We also recommend that you update your PHP version to at least 7.2 because WordPress 5.2 requires at least 7.2 (https://wordpress.org/about/requirements/). This could possibly be the cause of the issue. In most cases you cannot update your PHP version yourself and need to contact your host about this. The upgrade process is an easy process and should be something your host can do for you without affecting your website or charging you for it. Here’s a letter you can send to your hosting company:
I\'m interested in running the open-source WordPress https://wordpress.org/ web software and
I was wondering if my account supported the following:
- PHP 7.2 or greater
- MySQL 5.6 or greater
- The mod_rewrite Apache module
- HTTPS support
Looking forward to your reply.`
Hope this helps. Kindly let us know.
