Couple questions (problems) with the newly vBulletin
 

Hello everyone how much you have! :)

I have a few questions about the new and the best software, so I asked you specific answers.

1. Should I delete the config.php file after the installation?
2. Via e-mail I received several messages "Database Error", and everything works well. What could be the problem?
3. Appears to me this message "In order to accept POST request originating from this domain, the admin must add this domain to the whitelist.". Why?

Thanks!

New user and I speak English, so you pray for understanding as regards the English language!

Regards to all!
