WordPress 4.7 & PTE 2.4.8 does not work

Hello,
I’m using PTE from years but it seem it doesn’t work anymore.
When I try to edit a pic, there is a shot “loading moment” (less than 1sec).
(see here https://www.dropbox.com/s/1z9ff35km2jtlha/002.png?dl=0 )

Then the tool apairs with no pic.
(see here https://www.dropbox.com/s/ww244ycokfa7dx0/003.png?dl=0 )

I cannot edit nothing.
Could you help me ? Is there any solution ? (sorry for my english)
