I have installed to my footprints subdirectory. If I choose to go, via the blogs tab, to the Blog URL I get the following error message for each of the four blogs.

Fatal error: Class rendererplugin: Cannot inherit from undefined class plugin in /home/httpd/vhosts/shadowfoot.com/httpdocs/footprints/plugins/renderer.class.php on line 26

If I use the Write tab I get

Fatal error: Class toolbarplugin: Cannot inherit from undefined class plugin in /home/httpd/vhosts/shadowfoot.com/httpdocs/footprints/plugins/toolbar.class.php on line 25

Searching the forums I couldn't see this error being reported.

It's probably something fundamental. My previous website was with my ISP and had no scripting capabilities, so I don't know much about php. I haven't manually edited any of the files, just letting the install script do so. I did have to chmod the _conf.php file. It is now

-rw-rw-rw-

whereas most files uploaded are

-rw-r--r--

Is this the problem or is it something else?
