javascript error slowing down page

Hi Johannes;
I had a quick look and no this seems unrelated to the JavaScript error (which would be better fixed anyway, but that’s not the question here).

The reason the page is slow (in my opinion) is due to 2 issues;
1. there is no page cache (this version Autoptimize does not do page caching), so consider installing a free page cache plugin.
2. the page is very “heavy” due to all CSS being inlined, the HTML alone is over 1MB big which for mobile is simply too much. I would certainly disable “inline all CSS” and consider enabling “eliminate render-blocking CSS” in which case you’ll either have to add “above the fold CSS” (which applies to all pages) or add “rules” on the “Critical CSS” tab.

hope this helps,
frank

Thank you, Frank for your prompt and helpful support! Much appreciated!

Would you recommend to buy the autoptimize pro version which features caching, then?

Best,
Johannes

There are free page caching plugins too you could consider, e.g. “KeyCDN Cache Enabler”. I’m biased obviously, but AOPro would indeed also be an option, because that also includes automated Critical CSS rules so AOPro tackles both those issues.
