Blank page when edit page/post, quick edit doesn’t work

Hi!

I have 2 sites on the same hosting, both of them are on WordPress 6.6.2, running Kadence theme, no cache plugin installed. While trying to edit the existing pages or creating a new page, got a blank page. Quick edit didn’t work.

I’ve tried the followings, but none of them worked except using “define( ‘SCRIPT_DEBUG’, true );”

• Clear browser cache, no cache plugin installed on the site.
• Tried in different browsers and incognito windows as well, didn’t help
• Add to wp-config.php the following, it gave me nothing, no debug.log file generated at all in /wp-content/ folder, no errors displayed on the site.

define( ‘WP_DEBUG’, true);
define( ‘WP_DEBUG_LOG’, true);

• Increase the memory limit, didn’t solve the problem
  /* Add any custom values between this line and the “stop editing” line. */ define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
• Install the Health Check & Troubleshooting plugin, in the troubleshoot mode, all plugins were disabled and used the WP default theme (2024 theme). this didn’t solve the problem.
• F12, console errors:

This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”. post.php

Exception: then I added this line to wp-config.php file, then I could edit the page and quick edit works. I know this is for debugging, not a real solution.

define( 'SCRIPT_DEBUG', true );

I don’t know how to fix this blank page problem. Hope somebody could give me some hints.

Thanks in advance
