Category links only produce server 404 error pages...pages not found? Why?
If linking within the software (mainly category browsing) is broken the SEO addon has most likely been turned on without all the steps to install SEO Addon being completed. The error you most likely see looks something like this:
404 Not Found
The requested URL /index/listings/categoryXXX.htm does not exist.
Where XXX is the category id.
You will need to either turn off the SEO addon in the Addon Management tool of your Geodesic admin tool or complete the SEO module installation instructions within the online user manual here:
and the following section of the admin tool:
ADMINISTRATION MENU > ADDONS > SEO > SETTINGS
