A forum already exists with your e-mail...
You can create only one forum with your e-mail,
but you can moderate several of them.
See it with other administrators.

I am an admin on one but not the founder. Other then that I dont remember the forum i created.

Hi,

Try reading this thread:
https://help.forumotion.com/t93821-lost-founder-s-password

I didnt exactly loose my password, I just dont remember what forum i created a few year(s) ago. Trying to make a new one and it gave me that error.

Sorry if im confusing my problem.

I see,

So do you know the password that you may had used whenever creating this forum, that you speak of?

If so, maybe you can back it up.

NOTE: You have to use the Email & Password that you used when ever creating the forum.

Once you get it, it'll give you a link above of the page that can redirect you to your old forum. Then you can delete. (ACP >> General >> Forum Deletion).

Thank you Sir Chivas. That made it work.

No problem. Anytime.
