How do I check if AMP is working after installation?

Answer

To see if AMPXF is working on your site after installation, do the following:

• Make your browser window into a "mobile size/viewport"
• Open a thread on your forum
• In the URL-bar, edit the url to have ?amp=1 at the end (see note below)
  • if the url has e.g. #post-XXXX at the end, remove that part first

Note: If you haven't enabled the "Use full friendly URLs"-option in the ACP (your urls contain index.php?), then you need to use &amp=1 instead.
