Today, I noticed a strange error text when I was looking out for posts from one of the contributors on the blog.

Have a look here:
Anil Gupta | Learn How To Make Money Online and Blog Well Using Our Blogging Tips.

you will see various 'Array' error text on 3 posts. The actual post looks absolutely normal but it looks strange when I view it on the author page link and also on the homepage (today I published a post from that contributor.)

Also, I feel that this is only happening with this account...Could someone answer with a solution?
