Classifieds Plugin not working...still.

Hey there,
I set up and customized the fields for the Classifieds plugin but for some reason none of the links like:
are working at all (even when signed into an account that HAS posted an ad). This is for a client so it's very important that this issue gets resolved ASAP.

This is extremely urgent.

Here is what I was already suggested, which I completed, but alas, it's still not working:

Can you go to Dashboard > settings > permalinks

then make sure they aren't set on default. Change them to post-name.

If they are already on post-name, just hit save again to regnerate the permalinks.

Hope this helps

Thanks so much.
