fvmuag is not defined at HTMLLinkElement.onload

    We noticed an issue with the setting: Merge Fonts and Icons separately after a recent update.

    On some sites the FontAwesome icons won’t load and on other sites it will fallback to a different font.

    We have unchecked this setting on the live site to remedy the issue but it’s having a negative impact on performance.

    We’re noticing the following error in console:

    Uncaught ReferenceError: fvmuag is not defined at HTMLLinkElement.onload

    Can you provide us any support so that we can turn the setting back on?

    The page I need help with: [log in to see the link]

    Hi,

    I see the fvmuag function on the link provided, however, I also see you are using wp rocket with the delay js option enabled.

    The JS Enabled option delays scripts, so things only get defined after you interact with the page. Since the font optimization expects them to be already defined on page load (before interaction) it throws the error.

    You need to exclude fvmuag on wp rocket delay js options.

    However, if wp rocket is working fine for you, then probably you don’t need FVM.
    FVM is for fine tuning of scripts and styles (manual) so those functions of wp rocket will interfere with it.

    Hello,

    Thank you. I was able to exclude the keyword fvmuag from delay and that fixed the issue.

    Depending on the site we will actually see better performance scores when using FVM for minification and WP Rocket for other things like delay and deferral, LazyLoad, Heartbeat Control, etc.

    For now we’ll continue using both.
