 299 Welcome to CBFW, I cant find my configuration file so im assuming you installing me for the first time<br>
 300 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
 301 config, cause that will make life easier.<br><br>
 302 However, if this is the first time you have run this app, then all is good with the world. All I need right
 303 now is a place where i can store my config. I search the following directories for the location of my
 304 configuration (webconfig)<br>
 305 <li> /var/run/glcas/
 306 <li> /var/lib/glcas/
 307 <li> <?php echo $underroot?>/var/glcas/
 308 <br><br>
 309
 310 As root, you must now create one of these directories and change the ownership of the directory to the web owner.
 311 (chown <?php echo $uid?>:<?php echo $gid ?> the_path_you_choose).<br>
 312
