Hello,
I'm having the same issue.
basically I have 2 sites on my hosting account, one root default site (update manager works fine) and the second site, is in a sub-folder on the root directory (giving update manager problems).
Warning: file_put_contents(/home/xxxx/public_html/MYSITE2/administrator/templates/khepri/index.php) [function.file-put-contents]: failed to open stream: Permission denied in /home/xxxx/public_html/MYSITE/libraries/joomla/filesystem/file.php on line 298
Failed to extract archive!
********************
so I have FTP'd in and temporarily provided permissions 777 to the file.php
Do you need to do something else, or give specific folders temp
777 access, I don't want to go in allowing everything full access.
i would really appreciate your help here, this is a great component.
thanks
Brian
