The 2 problemas occurs when you try to enter with http://agressor.sytes.net
The first problem is that the new messages are erased, for example: when you log in, it says New messages (54) and when you post something, it says New messages (0) without even checking all of the rest messages. By entering directly to http://agressor.tecnoweb.com.mx everything goes perfect.
The second problem is that the favicon won't appear, but by entering with http://agressor.tecnoweb.com.mx it can be seen.

Server configuration:


What I'm interested in is that the website functions perfectly from the direction http://agressor.sytes.net
I hope I have been the most clear possible and I hope that someone can help me with this.
Thanks in advance!
