I have the exact same problem, m8. Ive just spent 3 hours going through this thread from the beginning. its an awesome contribution (it was working before i moved my shop) and im a php noob and even i can see the effort that went into the commenting, coding and install guidelines....but this issue...
it seems so simple, i kept trying to reset my seo url cache as initially thats what it must have been, right?> apparently wrong. im thinking now where the .html re-writes come from and deleting it manually so it can start afresh again...
as an aside i have changed my directoiry in the .htaccess from /test/ to /eshop/ have you made the appropriate changes for a root install in your .htaccess?
if anyone knows why i cant reset my urls it'd be cool if they could help cos i really love this contrib and want to keep using it!!
cheers,
rushy
