Well I browsed and only found posts from like 2011 on how to fix it. I have a custom theme and sometime ppl get ''Authorization code mismatch. Are you accessing this function correctly? Please go back and try again.'' when they login and sometime not. same for me. Idk what causes this and i'm having trouble understanding how to fix it. it would be good if you could help :3

You need to make sure you have included the desired line of code in every form as outlined here:

If you are having trouble identifying the forms and including the code then an alternate shortcut method is:

If even that doesn't help then I am afraid you need to bypass the check (not recommended) as it has been observed in some host that the code gets changed in every page load. There is a brief guideline on how to make the code static so that it can match:
