Error: table is marked as crashed

Hi @hugotisera,

This may be happening because of a plugin that may be accessing this table so frequently and may not have all its queries optimised. Below I have given a link of a thread that discusses similar issue. You may want to also contact your hosting provider and restore the database with a complete backup taken before doing so. Also the suggestion about the Query Monitor Plugin may be useful here to detect the plugin in question.

Here is the link to the thread:
