SippingSardinia

I have the same problem like Camila!
My https://sippingsardinia.com/wp-admin/ is blank and there is no admin options after I logon.

Can some one help with this issue?

Many thanks,
Aga

Thanks for quick answer.

I put this code but it is not actually working. WordPress sees the small files but not bigger dimension like 3906×2602. It is strange as I had no problem with those files before. I have check wp-content/uploads and all photos are there but when I want to edit them, wordpress is asking me to upload the photo again.

Any suggestions?
