We all know that SharePoint doesn’t support saving publishing sites as a template. I don’t recommend doing that anyway as the produced template will have errors and isn’t reliable to be used in production to create new sites off of. However, sometimes as a developer you need to save a publishing site as a template to see how SharePoint packages things. This can help you build your own custom web template which is a neat thing and replaces the need to save a publishing site as template.
Well, since the Save site as a template option is hidden from the publishing sites settings page we all used the following URL to go there directly:
Well, that is not going to work anymore in SharePoint 2013 if your site is a publishing site or have the publishing features activated. You basically get that following error: The “Save site as template” action is not supported on this site.
In order to get around this issue you need to update a single property page value in your SPWeb object for the site you are trying to save as a template and you are good to go. The property is called SaveSiteAsTemplateEnabled. We need to set that property to true that’s all. This can be done in powershell.
# Get a reference to the target site
$web = Get-SPWeb http://Intranet.SPmcse.com/Publishing
# Update the property bage value and set it to the string value “true”
$web.AllProperties[“SaveSiteAsTemplateEnabled”] = “true”
# Commit the property change to server
Now if you navigate to the Save site as a template page using the URL directly it will show fine and it will allow you to save the site as a template which stores a copy in the Solution gallery of the site collection. Make sure you have enough space in your C drive temp folder because it uses that location as a staging directory.

I debug further to find out where the problem. I downloaded the saved wsp’s from /_catalogs/solutions/Forms/AllItems.aspx to my desktop. Renamed it to .cab. Extracted all the contents and found some interesting facts along with manifest.xml file like List Instances, Modules, Property bags, web template. Inside List Instances, I found ElementsFields.xml Once I opened the above xml file, search for the check boxes and found the following
Further exploration on this, it seems that the checkbox attribute is invalid and needs to be modified.
Remove that affected column / remove the affected content type – does not require IISRESET also.
