Comodo (just recently) has blocked me from uploading some files via my FTP program Filezilla. It uploads the file but not the contents of the file. So when I visit a page I’ve uploaded, it just appears blank.
When I set Comodo to Allow All, it uploads fine. I have enabled FileZilla through Comodo but is that enough? Do I have to allow a port?
I had a read of your links and it didn’t really help. Mine doesn’t return a critical transfer error like that topic link you gave. It uploads but only an empty file…
