Got this error when trying to installing a module in Joomla:

Warning! Failed to move file. Unable to find install package

Cue half an hour of searching through forums and changing every folder to 777 in an attempt to check write permissions.

And what do you know, write permissions it was. Well sorta. If you've already changed all the permissions on your folders, try the following solution. It could be a tmp folder that Joomla is actually unable to write to. The problems stems that in some shared servers, Joomla picks up a tmp folder specified by php.ini, but that is outside the web root. So if your webroot (where Joomla is installed) is:

/home/www/843683/joomla

your tmp directory might be

/home/www/843683/tmp

Although it will show up as having write permissions enabled, try switching your tmp folder to within the webroot. I.E:

/home/www/84683/joomla/tmp

Create the directory in FTP and change permissions on it to 777. It probably already exists if you did the default Joomla install. Now go to your admin panel and in global configuration select 'server' and fill out the FULL path to your new tmp folder.

Hopefully this will have solved the issue for you.
