Hi,
This issue is usually caused by one of the following conditions that need to be checked.
To troubleshoot this issue, follow these instructions:
-Increase your memory limit to 512MB or more. You might need to ask your hosting provider to increase this limit.
-Go to Elementor > Settings > Advanced and enable Switch Editor Loader Method.
-Under WordPress Dashboard > Settings > General, confirm that the entry in the WordPress Address (URL) and Site Address (URL) fields are identical.
-To identify a plugin conflict, deactivate all plugins apart from Elementor and then reactivate them one by one to find which plugin is causing the issue.
-A program installed on your computer (System software and antivirus) might be causing a problem with Elementor or Elementor Pro. To rule out this possibility, check the web site with a different computer.
-The PHP max input vars must be increased to at least 3000. To change the maximum number of input variables, use a text editor to add the max_input_vars directive to your php.ini file.
-Does your system meet Elementor’s system requirements? These requirements include confirming that the PHP version is 7.4.x or later, a earlier version can cause some issues.
Let us know if that helps
Thank you for this – it was the gt3-themes-core plugin.
My content is back but I need to edit it without that said plugin.
