[ic] switching from low traffic to high traffic

[Sim Zacks]

I am using a modified version of simple, which was working great until I switched from low traffic to high traffic. 
Now I'm having problems.
1) When I restarted the server it says "Configuring catalog simple...Variable: read from non-existent file /home/machon/catalogs/simple/config/brown1/menubar, skipping.
In line 0 of the configuration file 'catalog.cfg':
Variable           MENUBAR       <menubar

done.
Interchange server started in INET and UNIX mode(s) (process id 4605)

the file /home/machon/catalogs/simple/config/brown1/menubar does exist and it works nicely in Low traffic mode.

Also it looks like a number of my variables aren't getting converted. For example my logo does not appear and when I look at the URL of the picture it shows {URL}/__LOGO__
Now it looks like a lot of the tags are not getting translated.

Hope you can help.
Thanks
Sim
