cadeauwerkplaats on "Polylang sudden fatal error"

Hi Chouby,
I changed the url in this messagebox, so that wasn't in the code.
I deleted the file, however now the message comes back each time while I'm uploading images.
So, it seems it makes the same mistake over and over again when it makes a new file.
Can you see what is wrong about it because then I can change it manually and maybe it is solve then.
