I've got a Joomla website located at www.mysdomain.com/site1/. I can't install extensions because Joomla can't write to the tmp folder. The tmp folder does have the right permissions drwxr-xr-x 2 web1 client1 4096 Apr 9 10:38 tmp. SuEXEC is enabled, and so is fast-cgi. What is the problem here? Any ideas? Can't I have a Joomla installation inside a "sub-folder" ?
