Development version 6.7.3
This is a bug fix version. A small bug in the Black Access List algorithm is fixed.
The bug: if you add the wildcard *.*.*.* entry (all IPv4 addresses) to the Black IP Access List, all form submissions including any login form will be denied with the request forbidden message and HTTP 403 code no matter what IP addresses the White IP Access Lists contains. The versions 6.5 and 6.7 are affected.
If you’re unable to install the development version do not use the wildcard *.*.*.* in the Black IP Access List.
