Hi there,
Thank you for the message. I checked the error screenshot and it seems that you use a plugin of some sort that minifies JS/CSS? Am I right? If that is the case you need to either avoid using it or exclude the Cornerstone CSS/JS files from that. The assets of the Cornerstone are already minified and using the plugins which minify those files will have the double minification problem and might cause issues.
I also suggest that you follow the steps below to rule out other possible reasons:
- 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.
- If you’re using a CDN, please clear the CDN’s cache and disable optimization services.
- 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.
- 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.
Get back to us with the result of the steps above and to follow up the case kindly get back to us with the URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post.
Thank you.
