Page Builder/Page Editor Broken

When editor or page-option is not showing.

It often cause of the corrupt media in media library.

You may fix this by accessing to the wp-config.php file using the hosting control panel / ftp editor program ( in the root folder where you install wordpress )

Then try adding this

define('WP_MAX_MEMORY_LIMIT', '1024M');

right after the php tag is opened ( <?php )

If it does not works, you have to remove it out instead.
You can see an example image of the corrupted media here.

*** Try removing only the blank media out ( You may have to remove it 2 – 3 times until it disappear ) ***
