removing author and dates on post

Have you asked whoever you got the theme from?

Unfortunately, these forums only support themes from this site here:

http://wordpress.org/themes/

But you can likely hide that line of text using CSS pretty easily – try using display: none; on the date/author element(s).

Since we have no access to commercial themes, can’t offer much else, sorry.
