Password switches between old an new every logout

Hello,

recently users told me that on my site members couldn't login so i tested it myself and noticed that every time i login and out my password switches between my current password an my old password.

I also tested to create a new account on the site with no old password and i noticed it switches between no password and current password.

my site/community builder uses Joomla logins and all users are synchronized, in the Joomla back-end it doesn't do that it works with my latest password.

I can not give my site because of this problem.

Does anyone know why community builder does this and how i can fix it?

Kind Regards

There is no functionality in CB that can do this. You've something installed probably triggering a user store after login for whatever reason. Typically would be a 3rd party User or System plugin.
