Still working on getting my page speed up with and getting gigged on the Defer parsing of JScript and others...but trying to fix one at a time. If I activate W3TC Cache, that fixes the defer issue, but then my layer sliders wont play/show the images on my pages. If I deactivate W3TC and activate Super Cache, the Layer Sliders work again but then I get gigged on the defer parsing again. So do you know of (1) if I activate W3TC how to get my layer sliders to work... or (2) if activate Super Cache if there is a configure somewhere to get defer parsing to work in that one ?

W3TC also fixes a couple other issues in GTMetrix so I would prefer to get that running BUT keep my Layer Sliders showing too. I have lots of those on my webpages and the main way people see my images.

Hello PaulAlford,

Thank you for contacting us about deferring javascript parsing with W3 Total Cache / WP Super Cache and its affect on your slider. Often, the real solution is reviewing the javascript that is loading and moving it to the bottom of your page, or in the footer for example. This will defer it, by causing it to load last(or later) since it goes from top down. The author of WP Super cache (when asked about deferring javascript parsing), suggested this very method. If you click the "Defer parsing of JavaScript" in GTMEtrix, it will list the javascripts that are loading, many of them look social media related.

You should be able to troubleshoot your slider in W3Total Cache by turning on debugging in WordPress. With debugging turned on, it is much easier to locate any errors within your WordPress site as well as any plugins and themes that may be causing errors.

If you have any further questions, feel free to post them below.

Thank you,

Thanks John Paul. I see that other plugin "scripts to footer" and tried that but it kills showing my images on the home page as well as kills all the layer sliders so I cant run that plugin. Is there a SIMPLE way to accomplish moving the "scripts" to the bottom of the page with a plugin (that doesnt kill other functions) or manually (if I can handle it). I am not knowledgable enough to do too much, just install plugin to do most of this technical stuff.

I did get W3TC running and a still have layer sliders working, but still getting gigged for defer parsing JS, gzip compression and, leverage browser caching...which I thought W3TC was supposed to fix. What else do I still need to do ?

Hello PaulaAlford,

I'm not sure how you setup W3TC, but you may want to go through this tutorial in order to set it up properly. Some of the items that you listed may simply be a setting that you need to enable if it's not seen as working. You can review our article using on using mod deflate (gzip compression). However, definitely review the settings that are mentioned in the tutorial. Other than that, you can request to have the site reviewed by our systems team in regards to optimization.

I hope that helps to answer your question! If you require further assistance, please let us know!

Thanks Arnel. I did look at that tutorial and went step by step with configure of W3TC and still getting same parsing, gzip and leverage browser gigs.... So does the Systems Team charge for the looking into Optimizing ?

Hello PaulAlford,

That type of optimization is not something our standard Systems team would do, but our Managed Hosting teamwould. That does, unfortunately, have a cost to it as they charge by the hour.

Also, if most things are doing well and you are getting a decen GT Metrix rating, don't worry about getting everything perfect. It is designed to show you the perfect values for a site, but most sites cannot meet all of those requirements. if your speed is good, it is nothing to lose sleep over.

Kindest Regards,
