Upload media not working in the new host

Hello,

I’ve moved my website in a new host (from local) and since, I can’t upload any media file.

I’ve already been looking on the web for solutions but without any result.
I’ve got the rights on the hosted file to write and read the directory. I’ve tried to change the name of the folder for “Store uploads” (in settings/media), but it’s still not working.
When I try to upload a new media, the following error message shows “Error saving media attachment”.

Thans you for your help
