Autoptimize slowed my site

Afraid that if you uninstalled and even restored a backup, the slowdown ultimately cannot have been caused by Autoptimize felipemm, all the more as it is supposed to do the opposite, making your site faster (although a lot depends on finding correct settings and on what numbers you’re looking at).

Now I did a quick test on GTmetrix and your main issue is long “time to first byte”. To tackle that you need a page cache, which Autoptimize is not. Try e.g. KeyCDN Cache Enabler or WP Super Cache. Once you have that installed your TTFB should be significantly better and we can think about next steps ??

hope this helps,

Thanks! It got a little faster.
Will using Autoptimize now work?

yes, it should, but some setting-tweaking might apply. start small e.g. with only CSS optimization and add additional optimizations step by step.

feel free to ask for guidance if you run into specific issues ??

After installing the plugin and enabling CSS optimization, the site was faster in the Mozilla browser, but in Chrome it was slower. And part of the menu does not load properly on the mobile.

faster vs slower is something which ideally is tested using a service like webpagetest.org, which allows one to run tests with multiple runs so you can compare median results of different KPI’s (main ones being “first paint”, “onLoad” and “first interactive”).

re. the broken mobile menu; try adding wp-content/et-cache to the comma-separted CSS optimization exclusion list.

Added however still not carrying the full menu on the inner pages for mobile.

OK, in that case also try unticking “minify excluded CSS/ JS”?

I was able to solve the problem as follows:
I created a new mobile menu with another CSS. I added “wp-content/themes/Divi/css” to the CSS optimization exclusion list.

Thank you very much for the tips.

you’re welcome felipemm, feel free to leave a review of the plugin and support here! ??
