When I click 'edit' icon for a category in my admin, I am getting this:
Catchable fatal error: Object of class queryFactoryResult could not be converted to string in /home/capralog/public_html/storefront/admin/categories.php on line 788

After reading posts, I already downloaded and installed the new html_output.php (dr. byte) but this is not doing anything....

Am desperate as I thought I grokked zencart but this is beyond me to fix -
will be glad to provide url if needed

thank you
