Hello,

How you have tried to install Joomla ? I have tried with Softaculous and installation completed Home

yes i installed but when ı try install theme or plugin, there are problems and if you can look Directory Permissions ,you will see unwritable folder :S. ( sorry for my bad english)

What permissions you have tried to use ? Try to set 777 and try install again.
