how can i fix this!!

[talkncaasports]

Is the "class_dm_visitormessage.php" file uploaded to the server? Is it the proper name? Is it readable (correctly chmod)?

usally means either the file path is incorrect on the php line.

That or the file that you are trying to call from php is not in that directory or the permissions are not set for EVERYBODY to read it.
i had the same problem on my website. all the files were there and all the php include information was correct. me the security of the directory was set so only administrator could read/write/delete the files doh. see if it wset to everybody read access
