Having an odd issue this am. My site (running v.1.5.5) is not allowing users to log in. When they try they get the login screen again, no errors. But when I try to create a new account, I get a "security error".
I've had some odd problems with the firewall yesterday (I use Sucuri for that) and they are looking into it, but I have active users logged in now and I am logged in just fine.
I don't see any errors in the ACP or in my server error log that might be associated with this. Errors that originate from my IP address, I mean.
I have support requests into my h0sting service and Sucuri, but am trying to cover all my bases. Any suggestions?
