Two problems with Classipress since upgrade to 3.0
I have got two problems with my site since upgrading to 3.0.
1) This is happening on one of my listing pages
"Catchable fatal error: Object of class WP_Error could not be converted to string in /home/pfworld/petfriendlyworld.com/wp
-includes/category-template.php on line 70"
2) On the advertiser contact form, it is not sending through the email address of the person who submitted the form. So if anyone receives a contact from their ad listing, it is showing the form as being submitted by the firstname.lastname@example.org
rather than the email address of whoever sent the form. I have tested this myself on one of our own listings and no matter what email address I enter as the enquirer, it is just coming through as being sent by email@example.com
