Classified "Posted By" does not redirect to the posters classifieds, it redirects to the d

my site has a number of running classifieds, if I were to click on the " posted by XXXX " i was previously re-directed to the authors posted classifieds.

Now, once I click on the author " posted by XXX " it redirects to the general page.

Ive added a screen shot as well as a loop-taxonomy.php

Please assist asap.
Much appreciated.
