Catchable Fatal error

Ok I got that post to go to the trash and all my others appeared. Then I tried to edit one and I got this error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /home/agproshp/public_html/wp-includes/formatting.php on line 3106

Now I see this:

Warning: trim() expects parameter 1 to be string, object given in /home/agproshp/public_html/wp-includes/link-template.php on line 3109

Catchable fatal error: Object of class WP_Error could not be converted to string in /home/agproshp/public_html/wp-includes/formatting.php on line 3106

I uninstalled 3.0.2 and reinstalled 2.04 and there was no change. I still have the error. Any chance of fixing this or do I need to remove the plugin?

I cannot delete FAQ’s either. I get this error:

Warning: parse_url() expects parameter 1 to be string, object given in /home/agproshp/public_html/wp-content/plugins/wordpress-seo-premium/premium/classes/class-post-watcher.php on line 249

Warning: Cannot modify header information – headers already sent by (output started at /home/agproshp/public_html/wp-content/plugins/wordpress-seo-premium/premium/classes/class-post-watcher.php:249) in /home/agproshp/public_html/wp-includes/pluggable.php on line 1196

What can I do to fix this?????

tried to add a new FAQ post, and got this error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /home/agproshp/public_html/wp-includes/formatting.php on line 3106

this error as well:

Catchable fatal error: Object of class WP_Error could not be converted to string in /home/agproshp/public_html/wp-content/plugins/woocommerce-product-faqs/admin/admin.php on line 240

Have you tried deactivating wordpress-seo-premium and seeing if issues still persist?

Yes, SEO disabled = no change.
Yoast analytics off = no change
re-saving permalink structure = no change
I have also opened each of the php files identified in the errors above and looked at the line referenced. I have removed any line spacing and deleted anything that appeared at the bottom of the files and added ?> to the end of each file. There is no change. I returned the files to the original awaiting response.
I can give you login info so you look at what is going on if you like, but this is a production site, cant leave it inoperable for too long.

I was looking at aother plugin and I wasn’t properly checking (in php) to make sure the variable as actually an array and not a string. The plugin was throwing similar errors to what we have here. Could it likely be a similar issue? Am I the only one with this problem?

this had not resolved. Any suggestions / ideas on how to repair?

Even if I try to save a FAQ as pending I get this error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /home/agproshp/public_html/wp-includes/formatting.php on line 3177

Is this problem only with my install? Is this being worked on? Please let me know, I really would like the plugin working properly. What info can I provide to assist?

Upgrade to wordpress 4.2.4 had no effect. Is this problem only on my site or are others having it as well? What can be done to correct it?
