Welcome to the Q&A Forum

Thank you all for your input. I couldn't agree more with everyone. Like I said, i needed to have more points of views to bring to the table.

Hi Diegopp, it looks like you might have a relation to this service you're promoting. If you do have a relation, could you please disclose the relation? Thanks! Also, it looks like this post was an abstract of http://www.cnet.com/news/qr-codes-arent-useless-after-all-nielsen-study-says/, where the original posters might want to go to find more information.

Sorry it took awhile to respond. I have found the error still existing using Xenu link sleuth tool. Not sure why webmaster tools doesn't detect it anymore, maybe it is being deindexed and will just take some time to go away. I will keep  waiting and trying anything i come across. Thank you for your help.

Well i am testing a couple things. 1. i change a link on my site to an existing page. 2. i deleted a "coming soon plugin that in not using. 3. i deleted an older sitemap i found in my ftp file manager. If none of this works then i have no idea what the problem is and will have to start eliminating plugins i guess. thank you all for the help,
