 * I recently installed the Network version of WordPress…so I have another learning
   curve I just started before installing 2046.
 * I installed 2046 through the Admin of the Network and enabled it for across the
   Network. I received the Error below. So I turned off the enabled across the Network
   and went to my sub-file domain through its Dashboard and enabled 2046 and received
   the same Error.
 * I’m still learning php so I’m new. I didn’t see what I could repair in the reference
   file which is also below.
 * Looks like a great program. Thank you.

 * p.s. Allowed markup allows for use of ‘code’ for formatting and then it says 
   to put code in backticks. Just put both in and now retrying with just backticks.
