As with other site speed optimization products, Slickstream needs to be excluded from PageSpeed Ninja's optimization. Here are instructions.
1. Login to WordPress and select Settings from the menu on the left. In the Settings menu, select PageSpeed Ninja.
2. Select the Advanced tab.
4. Look for the textbox labelled Exclude files list. Add embed-nav.js on its own line in the textbox.
5. Scroll back up to the top of the page and hit Save.
Note, you may need to clear your CDN cache to see Slickstream components on your site after making these changes.
If you have any problems or these instructions are in any way unclear, please contact Slickstream directly at firstname.lastname@example.org.
