Hi,
After an update using LiveWriter, I'm getting 3 exceptions appearing in the EventViewer for the site. The update works fine by the way..
The log states:

There is only 1 portal (0).
Any ideas?
Thanks for any help.

Hi,

Thanks for the reply.
In fact the other 2 errors are exactly the same as the one I posted, all from the 1 update.
The database hasn't had any changes re databaseOwner or object qualifier, its a standard DNN 4.9.5 installation.
Thanks for the help.

This is just a quick followup regarding the resolution to this issue.  I've included the text of an email I sent to Anthony in case this issue is experienced by other metaPost users.  I replaced the actual domain name with orgname since this was in response to a private email from Anthony.  Thanks Anthony!
______________________________________

Having host level access to the site helped me identify what the issue was.  The portalalias for this portal is orgname.com, which means that the posting URL used in WLW needs to be in this format:

 

http://orgname.com/metapost.ashx?key=text/html&sid=368

 

rather than this

 

http://www.orgname.com/metapost.ashx?key=text/html&sid=368

 

I wrote code to handle this situation, but the routine which does the actual lookup to retrieve the PortalId from the alias was logging the errors as it attempted the first URL entered.  I’ve updated metaPost so that the errors won’t be logged. 

 

Sorry about this confusion.  Until the next release is out, you can prevent the errors from filling your event log by deleting any old WLW accounts that were configured to use www in the URL and re-creating them.  Deleting and re-creating a WLW account has no effect on the content in the site, so this is a safe operation.

 

Thanks for your patience while we worked to solve this issue and for taking the time to set up a test account!
