Elementor Frozen Screen
There are three common issues to investigate when your Elementor loading freezes on the white screen.
2. Go to Elementor>System Info and check your PHP version. It should be 7.2 or higher. ( As of 12-20-2018) The version will change as new PHP versions are released. This can usually be upgraded through your CPanel or calling your Host and asking them to update it..
3. Go to Elementor >System Info and look for the value in WordPress Environment Memory Limit. It should be 256m or more. Elementor and it’s plugins take more memory so this is a common obstacle. You can change the Maximum Memory in the wp-config.php file. You can access this through an FTP program like filezilla or through your CPanel.
This video will walk you through the process to change the memory. https://www.youtube.com/watch?v=WmlGHje1V50
4. If you entered HTML or PHP code into a widget and the code has errors, this can also freeze the page the next time you go in to edit. You may have to edit in WP to remove the code. Or If you did short code insert, go to the short code and modify it there.
Hope this helps..
