the first error is causing the other errors on the page, so that one realy the only important one.
the first error is:
"Warning: set_time_limit() [function.set-time-limit]: Cannot set time limit in safe mode in /home/humanemo/public_html/contact.php on line 25
This means that the host has turned Safe Mode on in the php.ini file.
CSS Form builder will not work in an environment with safe mode turned on. Turning safe mode on disables some of the functions needed by the portion of Form Builder that sends the email, in this case the set-time-limit() is the disabled function.
For CSS Form builder to function properly, Safe Mode will need to be turned off on the php server, you will need to contact the host about this.
