I tried copy pasting the earlier fix, didn't work. All you need to do is remove one of the "a8devminor" and the "prefix".

This is the solution:

Open /arcade/functions/tar.php

edit the line :

var $tar_unpack_header = 'a100filename/a8mode/a8uid/a8gid/a12size/a12mtime/a8chksum/a1typeflag/a100linkname/a6magic/a2version/a32uname/a32gname/a8devmajor/a8devminor/a155/prefix';

to

var $tar_unpack_header = 'a100filename/a8mode/a8uid/a8gid/a12size/a12mtime/a8chksum/a1typeflag/a100linkname/a6magic/a2version/a32uname/a32gname/a8devmajor/a8devminor/a155';

in simple english, remove the /prefix that gives the error

I did that and everything works fine, on both www.yourforum.gr ( IPB 2.0.4 + Cyber's MOD Arcade ) & www.invisiongames.org ( 2.1.7 + ipbcoding.com Arcade 6.1.0 )

The issue is not the arcade but the TAR unpacker
