Wordpress - /wp-admin/post.php page goes blank when you try to edit a post and save it

I’ve been facing a strange problem in Wordpress. When I try to edit a post and then save it the page /wp-admin/post.php goes blank, the post was saved though.

However I could go back to the Admin and access other menus normally.

It happened when I moved my blog from one host to another.

First I thought it might be file permission problem but it turned out not to be a file permissions problem.

With Internet search and some debugging I discovered that All in SEO plugin was causing problem which I discovered by disabling all the plugin and enabling them one by one.
