Great work man!
I am following reports of problems but does not seem to have been reported this problem: the three buttons, Clear Cache, Update and Backup in the local installation reporting the message Not Found as screensaver Screensaver 2015-08-07 09:53:09
OK in the online.
This happens with Grav 0.9.35 and 0.2.0 Admin Plugin: installations with no errors.
FYI I work on a computer with Ubuntu 14.04.3 LTS Ubuntu and PHP 5.5.9-1ubuntu4.11 Development Server, both with the latest Chrome and Firefox 39.0.3.
In the console of Chrome the message is Failed to load resource: the server responded with a status of 404 (Not Found)
Thank rhukster and w00fz for the help, sadly I had lost the ticket # 3.
I installed Apache 2.4.7-1ubuntu4.5 without problems and, during the configuration to meet the requirements apache, I modified AllowOveride into AllowOverride. Now the buttons work great 
thanks again
Glad you got it all working again!
