I registered on this site in September. I like to use Opera, but I was forced to install Firefox specially for your site because of annoying bug.
When I try to log in from Opera, I receive the Error 300:
https://secure.wowinterface.com/login.php
The certificate is not known by its supposed issuer. It is not valid. In the worst case it may be used by criminals for fraudulent purposes. The website owner must immediately replace the certificate.
How can I fix this bug and deinstall the monstrous Firefox? =-)
