undefined function adonewconnection()

[gatux]

Dear All
I try to install but I get a msg like that:

Fatal error: Call to undefined function adonewconnection() in /home/gonzalez/public_html/leto1/inc/inc.DBAccess.php on line 83

I have tried many things, such as upload again all the files, etc.

Issues : receive a error massage as described above.
Steps to get the error msg : just try to start the dms
