[Logicampus-general] Fatal error: Call to undefined function: apache_request_headers()

[<vic...@so...>]

Hi everyone!
It´s me again :-) 

Now, I could finally get out of the database problem :-)
When I clicked the start now link (it says something like that), this 
message appears!
Fatal error: Call to undefined function: apache_request_headers() in 
/www/docs/ligadelconsorcista.org/public_html/logicampus/logicreate/lib/LC_us 
er.php on line 167 

That line says
print_r(apache_request_headers()); 

Where is the problem?
I already visit the forum, and found that another guys had similars problems 
at the very begining with apache_request_headers(), but it was not the same 
one...
Can anybody help me??
THANK YOU VERY MUCH GUYS!!!!
