Long time editing post

Hi @max12121

Thanks for reaching out! I know it’s painful when you upgrade your WordPress version and this breaks your website or create issues like slowdown your website.

Add the following lines of code:

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

After enabling this, you will able to identify potential plugins or theme conflicts with WP version 6.8, if you share the error code, then we can specifically guide you, how to fix the issue.

Best regards
