Save Site as template while Publishing Feature is activated

Problem

Saving a Site Template with activated Publishing Feature is not possible in SharePoint 2013 (menu link missing).

When using the direct browser link (which worked perfect in SharePoint 2010) http://YourSharePointSite/_layouts/15/savetmpl.aspx you get the error The „Save site as template“ action is not supported on this site.

Solution 

Modify the SaveSiteAsTemplateEnabled property in your SPWeb object via PowerShell.

# Store your Site in a variable:$SiteToModify = Get-SPWeb http://YourSharePointSite# Display the current value of the property:$SiteToModify.AllProperties["SaveSiteAsTemplateEnabled"]# Set the property to true:$SiteToModify.AllProperties["SaveSiteAsTemplateEnabled"] = "true"$SiteToModify.Update()

When now trying the savetmpl.aspx link again, you can save your template:
http://YourSharePointSite/_layouts/15/savetmpl.aspx
