I believed all these days when my site with domain was settled that this blogspot site was also fixed. I was wrong. Today, i got a task from PPP for this site, after a long lull. I was about to submit it when the submission failed. I was frustrated because the same error displayed to me a week ago and until now, and i quote:
"1 error prohibited this opportunity post from being saved
Post url hostname must match the selected blog
Haler, i was right when i posted the task to this site.
