 * I was doing a fresh install of 3.03 on WP 4.3.1 with PHP 5.3 but when I went 
   to activate the plugin I was presented with the following error:
 * Stream: Could not load chosen DB driver.
 * Help?

 * Hi Noice13 – best thing to try is downloading a fresh copy of Stream. Sounds 
   like there’s a file missing.

 * I uninstall the plugin and reinstalled it by uploading the zip file. Sorry to
   say same error message. The error message appears to be thrown by class-plugin.
   php when it builds the connection to the database. Where is the database connection
   define (name, table, etc)?
 * Thanks

 * Hi Noice13,
 * What version of PHP are you running?
 * You’re right that it’s thrown by `class-plugin.php`. Using the autoloader (which
   is registered a few lines earlier), it tries to instantiate the class `DB` (namespaced
   it’s `\WP_Stream\DB`. If you’re version of PHP is less than 5.3, then it won’t
   support the namespacing and thus won’t work.
 * But you should have been notified before that happened that your PHP version 
   is too low.
 * Try debugging around lines 77 – 79 – try to `die()` early, if the class exists,
   for example.
 * Also, are you sure you’re running the latest version of Stream? 3.0.3?
