[pmwiki-users] Site wanting login

This appears to be a message from the UserAuth addon.

Looking at the source code, you may be able to allow changes of the IP 
address during the same session with such a line in config.php, before 
including the userauth2.php file:

   $UA2EnforceFixedClientIp = false;

If an IP address changes in the same session, either:
1. you actually changed IP address (may happen often if you use mobile 
3G/4G internet, on the move, or if your device disconnects and 
reconnects a little later, or you passed through some load-balancing 
proxy), or
2. someone else was somehow able to hijack your session ID and is trying 
to access the wiki.

In the past IP addresses changed rarely during a session (~ 20 min) so 
the addon considers this risky.

If you configure your wiki to redirect all visitors to the HTTPS/SSL 
version, the risk of having your session ID stolen is much lower.

By default, PmWiki doesn't restrict a session to a single IP address.
