If you get this trouble on a Publishing page, page status will say “This page has been declared a record or placed on hold and is locked as read-only.” and you will not be able to edit that page. It is blocked.
To troubleshoot, go to Pages library and seee if that page is not checked out by “System account”. System account means App Pool account, it can happen to the best that someone is browsing a site as this account – which normally should not happen.
You will need to find out app pool account login and password or ask sytem administrator to check in that page for you.
So, as you see, it has nothing to do with Records management, it is just typical misleading SharePoint error message.
