http error 500 preferences action

[GoogleCodeExporter]

What steps will reproduce the problem?
1. login as a user
2. click Preferences
3. error occurs

What is the expected output? What do you see instead?
Expect to see a preferences window where i can adjust settings. Instead i see a 
http error 500 message. "The website encountered an error while retrieving 
http://<myurl>/miningbuddy/index.php?action=preferences. It may be down for 
maintenance or configured incorrectly"

What version of the product are you using? On what operating system?
MiningBuddy Plus 0.8.8.62 on Ubuntu 

Was this an upgrade or new install?
This is a new installation.

Please provide any additional information below.
As far as i can see the other features seem to be working properly, except 
perhaps where the preferences settings are needed.

Upon debugging the preferences class, i noticed a curl error. php5-curl wasn't 
yet installed as it is not mentioned in the installation requirements. I would 
suggest you added that to the readme.txt

Issue solved.

I'm having a white screen error with my preferences screen.  CurlSSL is what is 
running on my server.  When I enable curl (thus disabling curlssl) it works, 
but breaks just about everything else I'm running.

Any thoughts on this?
