Forum auto change version ???

My forum sometime auto change version and error in appearance
I must go to ACP and click green button in CSS tab to get back right version of my forum

Ex : My forum is Phpbb2 sometime it change to Invision or Phpbb3 !! It make me sick !!
My member confuse and don't like it !!
Everybody help me !!

There's no way your forum does this on it's own. Does someone know your password?

Do you change it yourself and accidentally save?

I check it very careful !! and my password is safe
Nobody log in with admin or founder to ACP
And watch in security list with no action change forum !!??

nobody can help me fix this problem ?
waiting .....

continued wait ... still wait !!

You have another admin with you?

Its possible they are going to Admin Panel // Display // Forum Version and change the version.
