The extension works fine, but there is a problem if users want to delete their ads.
It doesn' work. Editing ads works

With Joomla build in SEF it works fine. I have deactivated the cache in the configuration and purged urls but this is not the problem.

Joomla 1.5.22 legacy and MP 1.4.6
ARTIO JoomSEF 3.7.6 -paid version
ARTIO JoomSEF extension for Marketplace - paid version

any suggest?

You can test it here
http://katzen.dtp-internet.com

It seems to be a prob with duplicates:
---
Real url: index.php?option=com_marketplace&adid=1675&page=delete_ad&Itemid=202
->the page to confirm deleting the ad
SEF: kostenlose-suchanzeigen/katze-vermisst/1675-testeintrag77/anzeige-l-ouml-schen
----
Real url: index.php?option=com_marketplace&adid=1675&mode=db&page=delete_ad&Itemid=202
->the page to delete the ad
SEF: kostenlose-suchanzeigen/katze-vermisst/1675-testeintrag77/anzeige-l-ouml-schen

I changed the option "Number duplicate URLs" in the parameter section. Now I hope that this will not increase duplicates to much.

I have same problem with 3.8.1

-Tray set in plugin Number duplicate URLs on ON
-if you do test ads with same name, remove duplicate
