We have a page where we use a lot of different ACF custom blocks / fields, including ACF wrappers.
When we click to update this page, the whole website goes down until its fully saved – which takes half a minute to couple of minutes.
While the update-button is loading and I go to console on the edit page it will show:
VM2831:1 GET urlremoved/wp-admin/post.php?post=169&action=edit&message=4 500 (Internal Server Error)
And if I open new window to see the website during this loading, it will show Database not connected. Sometimes 504 Gateway Time-out.
The error logs say:
PHP Warning: mysqli_real_connect(): (HY000/2002): No such file or directory in /var/www/urlremoved/wordpress/wp-includes/wp-db.php on line 1753
Im not sure what to do to not have this happen, we tried increasing some php settings but that didnt help.
