Hi,
The reason is probably due to some lines in the httaccess file protecting your site from a brute force attack directed on the wp-login.php file. It took me some time to figure that one out.
I have the same problem. Sometimes it works sometimes not. I am considering renaming the wp-login.php to something else or redirecting the login to an other file which is not targeted in the brute force attack.
I am having some questions for myself btw but I really don’t see how I can post a new topic here.
My compliments to the builder of this template. I must ay that I am very impressed by both the template and his very patient support. Even though I think some ppl really should research a bit for them selves before asking questions that are either in the manual, the forum or all over internet.
