I just install SJ News Quickstart 3.1 package and I have very bad suprise from extension panel... I can't install Sjcore, YT framework or update Joomla and I take error messaje like this:

JInstaller: :Install: Failed to copy file /var/www/vhosts/balyozhaber.com/httpdocs/tmp/plg_system_sjcore/sjcore.php to /var/www/vhosts/balyozhaber.com/httpdocs/plugins/system/sjcore/sjcore.php

Then I don't see any image like SJ News Demo... I can view my site but I can't see any image...

YTTemplateTools::writeToFile - Can't open file: /var/www/vhosts/balyozhaber.com/httpdocs/cache/212252bdd119fcb2cf92489467906fda.jpg

I can't see images of site main slider and any other images... When I click on the any images this error occured:

YTTemplateTools::writeToFile - Can't open file: /var/www/vhosts/balyozhaber.com/httpdocs/cache/212252bdd119fcb2cf92489467906fda.jpg
