In my wordpress multisite, in the main website, I got error when I tried to update any post or widget. When I put my site in debug mode, I found many error with: The table is full for query UPDATE or INSERT as:
- WordPress database error The table ‘wp_1_options’ is full for query UPDATE
- WordPress database error The table ‘wp_1_comments’ is full for query INSERT
- etc
And I think each table of my db seem limit contain only 3MB if I checked to the content of those error tables.
I use a database plugin for my wordpress site to check the db, I found most of them got “Overhead” size of 3MB.
What is the exactly issue with above info? How we could solve it?
What does Overhead mean? How can we solve that overhead issue?
