 324 <h1>Welcome to GLCAS</h1>
 325 Welcome to GLCAS, I cant find my configuration file so im assuming you installing me for the first time<br>
 326 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
 327 config, cause that will make life easier.<br><br>
 328 However, if this is the first time you have run this app, then all is good with the world. All I need right
 329 now is a place where i can store my config. I search the following directories for the location of my
 330 configuration (webconfig)<br>
 331 <li> /var/run/glcas/
 332 <li> /var/lib/glcas/
 333 <li> <?php echo $underroot?>/var/glcas/
 334 <br><br>
 335
 336 As root, you must now create one of these directories and change the ownership of the directory to the web owner.
 337 (chown <?php echo $uid?>:<?php echo $gid ?> the_path_you_choose).<br>
 338
 339 Now, tell me where you want me to create the webconfig file:<br>
 340 <form method="post">
 341 <select name="installdir">
 342 <option value="/var/run/glcas">/var/run/glcas</option>
