Save Site as a template fails - Not a publishing site

I tried saving a lightly customized team site as a template but no matter what I did, it failed.


I tried it from the site settings.


I tried PowerShell:
asnp *sh*


$Web=Get-SPWeb https://webapp/sites/template
$Web.SaveAsTemplate("TeamSiteTemplate10.3","TeamSiteTemplate10.3","TeamSiteTemplate10.3",1)


Which failed with this error:
Exception calling "SaveAsTemplate" with "4" argument(s): "Error generating solution files in temporary directory."


Long story of troubleshooting omitted. Here is what I found to be the issue: Document Parsing is disabled to prevent a required field to prevent Office docs from allowing drag and drop updates--a workaround that keeps biting me.


Once I ran this:
asnp *sh*


$Web=Get-SPWeb https://webapp/sites/template


$web.ParserEnabled = $true


$web.Update() 


I was then able to save the site as a template successfully.
