I have searched a lot for similar solutions for this problem but with no luck. I am simply trying to post new basic-page that contains an image (uploaded to my site or another site -- it did not make difference). Once I click "Save" I get nothing but blue border on the top of the page and a message says "The specified URL cannot be found. ". What could cause that? I am using Drupal 7. Any Ideas?
Update:
I am using Drupal 7.19
i have checked site by another demo domain/server and it is working good. but not working at actual domain/server.
