Have some problems with file uploading, both images in TinyMCE and images in the Files and Images tab.
I got an error (in swedish, but something like) "file in not valid". I saw on the forum that some have had this problem in 2.4.1 version, but I have 2.4.2 . Anyone who have this problem or knew a solution?
Now I have to upload every file manually via FTP before I can use them, but it works.
