Support » Plugin: Autoptimize » (Not So Much of a) Nightmare (Now!)

  • Been keeping tabs on Autoptimize ever since I gave it a 2star review a couple of years ago.

    Re-tried it again many times, blew up websites many times, and to be honest, I couldn’t work out what all the fuss was about. There was no clear documentation and minimal settings to adjust, and I’d given up on it.

    Then I enrolled in one of these online Udemy courses. When I saw that it involved using Autoptimize, I was a knife-edge away from asking for a refund!

    Having followed some excellent coaching and teaching, I can now see where a lot of the acclaim was coming from. Infinitely better at minifying than W3 Total Cache, when the instructions are there to use it at full throttle, it’s an excellent plugin!

    I’m still only giving it 4stars though, as there are obvious improvements that can be made to the UI.

    If only there was a way to async javascript without using 3rd party code, and if only there was a way to add files to exclude from being optimized (a la W3TC’s help wizard feature), this would truly be a 5star plugin – even if it were a paid option for these last features!

    Have you considered posting in that plugin’s dedicated support sub-forum for help?

    Hi Steve; Autoptimize is not a plug-and-play plugin, in some cases configuration (and trial-and-error) are needed as described in the FAQ. If you want I can guide you through the process.

    @jan – no, I only installed on a whim to see what the rave reviews were all about. Its not essential that I use the plugin.

    @futta – after installation:
    1) Checked all initial settings, website disappeared.
    2) Checked just HTML setting, website disappeared.
    3) Checked just CSS setting, website disappeared.
    4) Checked just JS setting, website disappeared.

    Methinks it’s a David Blaine plugin!

    David Blaine? Yeah, guess Autoptimize is magic after all 😉

    No seriously, don’t think I’ve seen reports about it failing that bad before … Let me ask you some questions to see if we can get out of that mess;

    1. When you write “website disappeared”, do you mean you saw nothing (blank page, even in HTML source) or that your website becomes unusable (some stuff is visible, but nothing really works)?
    2. Can you check your PHP error log, anything about Autoptimize in there?
    3. What stack are you running on; Linux+Apache or Windows+IIS or something less obvious?
    4. Are you running any other caching/ minification plugins?
    5. Can you enable the old minifiers by adding

      in your wp-config.php and then try CSS and JS optimization (one after the other) again to see if that changes anything?

    By ‘website disappeared’, I mean that the url loaded up but the page was blank.

    Running Linux+Apache on GoDaddy

    Using W3 Total Cache

    Might seem a silly question, but where is the php error log?

    After placing the code into wp-config.php:

    Optimize CSS code now works, but JS enabling just gives a blank page again.

    Well, CSS works, that’s a start at least 🙂

    Regarding W3TC; do you use CSS & JS (& HTML) optimization in there? If so, can you disable that (to avoid conflicts)?

    Regarding PHP error log; that depends on the config of your server. A quick web search learned me that GoDaddy PHP error logs are off by default, but you can enable it for a 7-day period.

    Regarding GoDaddy; are you on shared or dedicated hosting? do you know how much memory PHP gets?

    Man, how I hate having a one-star-rating … B-)

    I’ve been working on 1.8 and have been adding code at least fail gracefully and avoid nasty breakage (blank pages and blank CSS-files).

    So if you happen to read thsi; 1.8.0-test has just been published, I would love it if you could test to see if anything has improved?

    Just back on a whim again.

    I’m now running a website that has a SSL certificate, and as we all know, this layer of security can slow up sites to a degree.

    I’m about to give Autoptimize another blast, so I’ll let you know what happens!

    Plugin Author Frank Goossens


    exciting times 😉

    let me know if I can help!

    First the good points:

    The HTML and Javascript options seem to work ok now, giving a speed boost of around 2 according to GTMetrix and Google Page Speed Insights.

    Now the bad points:

    The CSS options are still utter rubbish though not QUITE as bad as when they obliterated the website. Now all the styling disappears but you can still see some of the content.

    Knowing that you don’t like one-star ratings, I’ll re-assess it to a two-star, purely because the website doesn’t totally disappear now, but I have a feeling that I’ll be using something else for site speed.

    Plugin Author Frank Goossens


    OK, regarding the CSS; are the optimized files empty, or is there CSS in there? Did you try the “look only in head”-option? could you add “.min” to the comma-seperated “exclude from CSS optimization”-list?

    Plugin Author Frank Goossens


    feel free to provide me with the URL to your site (here or via futtta at gmail dot com), I’ll be happy to have a look myself.

    I tried every option and combination one by one, all with the same result of a white page with a list of contents.

    Adding “.min” has no effect.

    Have just sent an email to make sure you’re receiving them.

    Plugin Author Frank Goossens


    I am 😉
