List template not showing up when adding an app

Problem:

The list/library template you just created by saving List or library as a template is not showing up when you try to create a new list/library based on that template.

One thing to check first is to go to the List templates Gallery (Site settings-> List templates under web designer galleries).

If the template in question does NOT have product Version and Feature ID assigned. Then the problem might be that the ParserEnabled property is set to false on that site.

Resolution:

Using PowerShell , set the ParserEnabled property to true.

$web = Get-SPWeb <url of web>
$web.ParserEnabled = $true
$web.Update()
