Hello
I use Codecharge to develop a php-mysql application and it was working fine until my hosting company changed their hard drive on their servers, then i started getting the following errors
Warning: mysql_pconnect() [function.mysql-pconnect]: User already has more than 'max_user_connections' active connections in /home/comkon/public_html/com/admin/db_mysql.php on line 99
Database error: pconnect(localhost, comkon_1, $DBPassword) failed.
MySQL Error: 0 ()
Session halted.
the specific line of code giving error is
/* establish connection, select database */
if (!$this->Connected) {
$this->Query_ID = 0;
if($this->Persistent)
$this->Link_ID=mysql_pconnect($DBHost, $DBUser, $DBPassword);
else
$this->Link_ID=mysql_connect($DBHost, $DBUser, $DBPassword);
if (!$this->Link_ID) {
$this->halt("pconnect($DBHost, $DBUser, \$DBPassword) failed.");
return 0;
}
if (!@mysql_select_db($DBDatabase,$this->Link_ID)) {
$this->halt("cannot use database ".$this->DBDatabase);
return 0;
}
I would appreciate some help here
Thank you

and if you have modified any of the common files yourself sometimes changing this in connections may not work - all the code shoudl be on grey background...
