Login to your ftp and change the file that you want to edit to 666 permissions..
What I mean is… change the file permissions to writable by chmod’ing it to 666. 666 will work and so will 744 or 755 I believe, not sure, I would use 666 if I were you
My FTP doesn’t use numbers. It has three groups, “Owner”, “Group”, and “Other”. Under each group it has “Read”, “Write”, and “Executable”. I checked them all, but do you know what the equivalent to 666 is? I checked and it says just Read and Write, but that still doesn’t allow me to edit them.
Read = 4, Write = 2, Execute = 1, and you add them up. The first number is Owner, the second Group, the third Other. So 666 would equal Read and Write for Owner, Group, and Other.
