Steps to reproduce the issue

• Setup a fresh Joomla 3.6.2
• Do not use a FTP account during the setup
• Do not install basic config
• upload a configuration.php and give write access
• finish joomla configuration
• delete the installation folder
• try to open the joomla main website -> You will get an error 500 (at least in my case)

Expected result

I would expect the default joomla website. I mean this isn´t my first joomla installation. Over the past years I have done multiple on the same 3rd party hosted webspace (mostly for development reasons).

Actual result

An error Server 500 (when I give 770 instead of 750 on the joomla project cache folder everything is working as expected)

System information (as much as possible)

see attachment (systeminfo.txt)

Additional comments

When I try to login into the Admin Panel I got the joomla error:

An error has occurred.
0 The file Cache Storage is not supported on this platform.

This joomla error was solved with giving write permissions as well to administrator/cache as mentioned here: http://forum.joomla.org/viewtopic.php?t=928829

Now i can work with the Joomla installation. No additional files where created in the cache folder. When I remove the permissions again, I will get the error messages again.
