All members getting banned page
 

I have a site that all my members are getting the banned forever page, I do not know what went wrong last night after I went to bed but got woke up early this morning with people wanting to know why they were banned. When I go to the site with a computer I have not used before I get the screen but if I use a computer I have used on the site before my cookies take me past that screen and log me in.

It looks as though the page has been replaced or something so that my members are getting this banned screen so they will leave. Please help.

Check your user groups. Did they somehow get set as a "Banned group"

The site got hacked and someone went in and changed the settings in the user groups. Took me a while to find it and all the other places they had changed but all is fixed now. Do not know why someone would want to mess up a site that is just starting out.

Dunno. Reset all the passwords and only keep you as the Admin for now. You'll learn who to trust as you go.

I suggest that you restore a backup from before the hack. Based on your description, there could be more places where he changed data that you have not found yet.
