Support » Plugin: Autoptimize » W3 Total Cache and Autoptimize setup

  • Resolved shaneshane


    I see a lot of people are having issues with using it along side W3 Total Cache. As i read through the thread, many deleted either w3tc or the autoptimize even though you suggested they don’t have to.

    As I can’t think of running my sites without W3TC, i would like to know what setup you would suggest on both the plugins so they can co exist. I am mostly interested in asynchronize JS scripts.

    The only possible conflict is if both plugins try CSS & JS optimization. So if you use Autoptimize, just disable W3TC CSS & JS minification and you should be good to go.

    hope this helps,

    And HTML minification, off course.

    Hi Frank,

    I am also using w3tc. After installing AO it looks like its doing a much better job on JS than w3tc.

    Of course I hoped it would give better results on CSS optimization too…

    However, when unchecking css optimization in w3tc, and using css in AO instead it blanks backgroundcolour, changes linkcolour and probable some more things. – Responsive Pro theme – Woo installed

    Any idea what I can do to make this work?

    Thanks, Arien

    Hmmm … some possibilities;
    * you could try to add “body.custom-background” and “#ff8944” to the comma-seperated CSS-exclusion-list, thus making sure that the inline CSS identified by these strings stays inline
    * you could, alternatively, add the “!important” to the inline styles, thus making sure that these still have priority even when aggregated in an external stylesheet
    * if W3TC does a good job of CSS optimization, you could keep on using that (and not AO CSS autoptimization)

    Groetjes (en voor mij een doppio graag 😉 ),

    Thanks a lot! Your 1st option did the job and you outperformed w3tc (13 requests less and approx. 100 kb less page size)

    Als dank een kortingcode kkem10 mocht je de lekkerste doppio thuis willen maken 😉

    groeten Ariën

    I’m using both. Works well though I feel my website is slower than usual. This is where it gets wierd. All major website speed testers said my website speed is very fast less than 2 seconds. Nothing is broken so…
