There are a diversity of custom error pages, such as 404. But what about other errors?
Sometimes my server (or it's database) crashes, most likely due to many Wordpress actions made in a short time. In such case any user will see the error message, as seen in the image below.
I would like to modify such page with clear instructions, instead of a big red box. But how would I create such error page?
Thanks!
Fyi, I use the 'Sentora' control panel.
