The plugin developer is not available at this moment and I hope I get resolution for my problem here These are the errors and many others are reporting the same error on the theme's official site > Catchable fatal error: Object of class > WP_Error could not be converted to > string in > /public_html/wp-content/themes/quality-control/single.php > on line 55 and some times... > Catchable fatal error: Object of class > WP_Error could not be converted to > string in > \wp-content\themes\quality-control\inc\templates\loop.php > on line 37 Could anybody help me with this? I am ready to give admin access to my site to replicate the error **Update :** The WordPress version I am using is 3.1 and I have tried both the 'Quality control' theme versions 1.5 and 2.0 versions . http://ffav.in is the address of web-site and these are the URLs for some example posts with errors : 1) http:// ffav.in/ticket/test/ 2) http:// ffav.in/category/uncategorized/ Thanks!
