Oh.. easy, it seems the blogger team is about updating the blogger website now, so just calm down. It happens so often lately. Just open your old almost forgotten browser, Internet Explorer try to access your blogger template through it, and try to update your template there. It works for me.

I can’t edit my post title.
In fact, I can’t have my cursor focus on the post title box.

Yes, and this also has the same answer as the first question. I’ve been there too. I can’t have my cursor focus on the post title box, so i can’t type anything. to solve this, just do exactly the same as the first answer above, try to access your blogger account from Internet Explorer. hope it works for you. thanks

next post, i will give you a cool blogger hack about showing comments link + the commentars under the bottom of each posts. stay tuned!
