MyBB Community Forums

Hi, I cannot log in to my forum. Every time I try, to log in, I get the "authorization mismatch" error.

I have tried every single solution possible to resolve this issue, including the pinned threads.

I have used 3 different search engines (Google, Bing and DuckDuckGo) to find the solution and tried the varying results in them. Including the results on foreign MyBB support sites.

I have even tried the "theme patcher" plugin which, was only effective at showing me a blank white page whenever I tried to activate it. (it didn't work, and as a result, it can only be manually uninstalled.)

I had been having this issue ever since I updated to 1.8.24, and when I first had this issue then, I waited for another update, and then eventually upgraded to the current version we're on now.

It still did not work.

I followed the suggestions in this topic:

https://community.mybb.com/thread-218862.html

and it was irrelevant because tag referenced in that topic, wasn't missing at all in any of the referenced templates.

What else can be done to fix this issue?

The forum isn't open, and so, I can send my url via pm if need be..

Thank you in advance for the help.

If you tried hard and nothing worked; you can disable / bypass auth code temporarily, like this way:

This is a security feature and bypassing is not recommended. Do it only if you are desperate and willing to take CSRF attack risks.
