Password keeps changing!!!

So, I have xenforo running, and it keeps breaking and I thought it was MySQL stopping because it used to many queries for the free plan.
If I try to sign in though it says my password is wrong, even thought it is not. I then change my password and it works perfectly, the website is fully operational.
This is infuriating, what would cause this? and no, nobody has access to my account

How exactly do you change your password? Please make sure you only change your password through the client area. The client area occasionally synchronizes the passwords to the hosting servers, so you need to make sure you passwords match.
