 374 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
 375 config, cause that will make life easier.<br><br>
 376 However, if this is the first time you have run this app, then all is good with the world. All I need right
 377 now is a place where i can store my config. I search the following directories for the location of my

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