OK, аз tmp я виждам, зададена ми е, но защо ми се появява това съобщение, което цитирах и по - горе....:
The PHP temporary folder is the folder that PHP uses to store an uploaded file before Joomla can access this file. Whilst the folder not being set isn't always a problem, if you are having issues with manifest files not being detected or uploaded files not being detected, setting this in your php.ini file might fix the issue.
