I installed WordPress 5 days ago and every thing is going perfect except one thing. I can't write posts with images or edit them. For example when I write a new post and add image on it, I can't save it because WP acts like I haven't changed anything and been quitting with discarding changes. It is the same for the posts that I made in Flickr. Although the images are on my host I have the same problem everytime. And there is one thing more, when I add tithe="_blank" to my links, it is deleted automatically. If I fix this, I will be very pleased. I've been working on it for 3 days.
