 350 Welcome to CBFW, I cant find my configuration file so im assuming you installing me for the first time<br>
 351 If this is not correct then we have a big problem that needs to be solved, i hope you have a backup of the old
 352 config, cause that will make life easier.<br><br>
 353 However, if this is the first time you have run this app, then all is good with the world. All I need right
 354 now is a place where i can store my config. I search the following directories for the location of my
 355 configuration (webconfig)<br>

 358 <li> <?php echo $underroot?>/var/glcas/

 360
 361 As root, you must now create one of these directories and change the ownership of the directory to the web owner.
 362 (chown <?php echo $uid?>:<?php echo $gid ?> the_path_you_choose).<br>
