I seem to have lost my connection to my database without my doing anything except load in a new zen cart into a new folder. I haven't done any connecting yet to database but have partially run an install to the point of reading the documentation.
Here is the log from today
[21-Jul-2014 20:29:55] PHP Fatal error: 0

B_ERROR_NOT_CONNECTED :: delete from zen_db_cache in .../includes/classes/db/mysql/query_factory.php on line 120
Could the creation of the new cart have anything to do with this? That is the only new thing I have done.
