I have installed the WP-Cleanfix plugin (been installed since the beginning of using my website) and I have cleaned everything but that in the "Table Optimize" section. It will NOT clean for some reason. I have 55629kb that I cannot clean.
I believe it was there when I installed a "Chat plugin" (cannot recall which one now, sorry), which I was looking at, but no longer required (just testing out various plugins). Now, it cannot clean in my WP-Cleanfix.
Can anyone suggest a way to clean this "manually" if need be?
Many thanks in advance for any help or suggestions here
