If you experience problems with your website after updating from older versions, simply restore the .htaccess file from the file .htaccess.backup, which is locate in the root WordPress folder. Then, deactivate/reactivate Visitor Maps Extended Referer Field. There was a bug which may have caused htaccess to be improperly written.
If you continue to experience problems, contact me for help.
Just a FYI: I just tried installing this plugin on another blog. When activating i got the following error: Visitor Maps Extended could not backup /home/content/53/9530553/html/naru/blog/.htaccess. The installation was terminated.
Maybe a check is in order to see if an .htaccess exists in the blog home directory, and if one is not found continue the installation. I have my .htaccess file in the hosting account root so it denies access to other services running, besides WordPress.
I think this plugin and especially the latest addition of IP and Referrer blocking is a great addition. Keep up the good work!
I made it so it would throw that error if there was no htaccess present in the root WordPress folder. This plugin relies on htaccess for banning IPs and referers. In the future, I will make an option so you can customize the path to htaccess, or write to multiple htaccess files at once.
