You ogtta stopleaving me to figure this s**t out on my own!! It is terrifying lol 😉

I found it and truncated the whole table. 

All of my table are on InnoDB except for Likes and visits, they are on My sam. 

Should i truncate the Likes table too?

This didnt work though, still getting slow load times 

Ive done all of this guys, but my site is still getting slow page load times due to slow queries......

How is this?

for question 2:

for question 3

I have most addons for wpforo, all of them are fully up to date except for the emojis, that's deactivated as i need to renew it. 

I dont think i have added any custom code to the function file either. 

I hope this helps 🙂
