I had a problem with ownerships on some directories, and I’m on a shared host, so I couldn’t change them with unix commands. What I ended up doing is install a third party “File Manager” onto my server and used that to change ownerships. (I actually installed Joomla with the File Manager plugin). You just have to find a file manager that allows change of ownerships on directories. You could also email the server hosting company’s technical support and ask them to change ownerships on directories. if they’re nice, they will do it.
zanzoon, if the ownership rights is the problem then I can’t help you. egerrits’ solution may be the only one available. There’s something wrong with having to rely on a host tech support people ‘being nice’ to solve what shouldn’t be a problem in the first place. (sigh)
