At the moment when not logged in I can't see other posts? I have one under electronics / computers / accessories/peripherals for a set of speakers but it doesn't show up in the list unless I log in first.
This is due to a proximity search error. The listing coordinates were being rounded off, and loosing precision; It works now (not deployed yet). The search works properly, and it is many times faster now because I migrated the code-based filters into database stored procedures. ;) This took all weekend to redesign, but is much more accurate and efficient.
I checked my listing and the location is Lindsay and so is my search.. I reset it just in case so I"m not sure why the radius search would be a problem?
Your speaker set is at -78.74, 44.36 and you are at -79.38, 43.65. That's a 94 km distance apart. My guess is if you drag the slider all the way to the right it would show. Update both your registered account and guess account locations as well.
They're in the database. I can make a special admin tool for it also for debugging - for instance, for only admins (you and I), hovering over the distance in the listing would pop up the details (good idea actually).
