There is a problem with app blocks & display data, need help

The app inventor does not work properly since yesterday, it does not accept blocks & there is a misorder of all components I have entered,
please resolve this for me so I can continue working on my app, thanks.

Please show your relevant blocks and indicate where the problem/s arise ?

How can i show that, there is no image upload to show you screen shot

There should be an upload button on your toolbar
