frank wrote Hi Don, I really do need this fix asap. I've rolled out MetaPost to a few users who are really depending on this for their daily work and upgraded to DNN 5.1 without checking MetaPost functionality. Please send me beta info. Thanks Frank

I use dnn5.1 also ,Please send me beta 
Thanks
 

Hi Don,

I'm having the same issue with Livewriter and DNN 5.1
Could you send me the beta ?

Many thanks,

Dirk

Well drat this is happening to me.  I have 1.3.6 PE.  metaPost is functional with my News Articles.  I am now ready to venture into text/html, but alas, the dreaded Server 0 error.  BTW my dnn version is 5.1.1CE.  I have not yet upgraded to 5.1.4.  Think that could be it? Please advise.
