I have just upgraded to 16.10 from 16.04. I currently have PHP5.6 installed and have just tried to run a command in the terminal which is throwing the following error:
$ drush cc all PHP Fatal error: Uncaught Error: Undefined class constant 'MYSQL_ATTR_USE_BUFFERED_QUERY'
When I search online for how to resolve this I keep finding results that tell me to enable things like the php5-mysql extension. However I already have these extensions enabled.
Does anyone know how I can debug this and resolve it?
