I think I found the cause of this as we were experiencing something similar.
We got the same results after deleting a category and something similar with emptying a category.
In adm-misc.php at line 3037:
Code:
Content visible to verified customers only.
should likely be:
Code:
Content visible to verified customers only.
The maindir is not needed as that is what is causing the /reviews/ before the full URL and that was what was giving us the 404. After the above update, after deleting a category, we get returned to the category page as in prior versions.
Similarly in the same file at line 3397:
Code:
Content visible to verified customers only.
doesn't likely need the Globals as well and I think that admcat=cats may need to be admact=admcats since we were getting two errors on our end. So we ended up with:
Code:
Content visible to verified customers only.
and that seemed to do the trick.
Chuck can you confirm for us what's above?
Thanks.
