Hi, I have a problem with images, 
i searched the forum and tried to do all of them. 
Deactivated the plugins, checked the permissions of the images 
but nothing. I don't know how to fix it. Can you help me, please? 
Thanks

Hi,
i just fixed it by deleting the siteground optimizer plugin. 
I had eliminated all the other optimizer as you had previously suggested, but that I didn't think would affect. 
Thanks for the attention.
Regards,
Antonella
