got phpslash running just fine, but I occasionaly (sometimes all too frequently) get a buttload of errors, which go away if I do a refresh.  Here's the first few errors I get:
 
Warning: Undefined variable: sitename in config.php3 on line 183

Warning: Use of undefined constant rootdir - assumed 'rootdir' in /home/digiraticafe/www/digislash/Variable.class on line 23

Warning: Use of undefined constant basedir - assumed 'basedir' in /home/digiraticafe/www/digislash/Variable.class on line 24

Warning: Use of undefined constant listvariable - assumed 'listvariable' in /home/digiraticafe/www/digislash/Variable.class on line 32

Warning: Use of undefined constant newvariable - assumed 'newvariable' in /home/digiraticafe/www/digislash/Variable.class on line 33

Warning: Use of undefined constant value - assumed 'value' in /home/digiraticafe/www/digislash/Variable.class on line 54

Warning: Undefined variable: siteowner in config.php3 on line 184

Warning: Use of undefined constant value - assumed 'value' in /home/digiraticafe/www/digislash/Variable.class on line 54

Warning: Undefined variable: xsitename in config.php3 on line 185

It goes on from there, too much to post it all.  I figure there's probably a cascading of errors based on one initial error..  I would attach the entire page with errors (from "view source" in my browser) but it's a rather big file...
 
My only thought is that maybe its a problem with the mysql server... perhaps my webserver is too bogged down?
