When clicking the password reset okay it tells me right away that I must wait 180 seconds, only it does send the email. When clicking the link in the email it says "Your password could not be reset. Please try again." but at least half of the time the password reset email is sent with the new password. Sometimes instead of the error I get a connection reset.
The link appears to be valid and the usual issue of the board url should be fine as its http://www.tbgclan.com I thought maybe the htaccess redirects for vbseo might be an issue tested without that. Only other thing odd ball is we have a cookie set so that things work with and without the www (all this tested on www. But the cookie is set to .tbgclan.com and xf_ as the prefix.
