Support » Plugin: Gravity Forms Advanced File Uploader » Your browser doesn't have Flash, Silverlight or HTML5 support

  • Hi, I’m getting this message in Safari on OSX, and Chrome and IE10 in Windows –

    Your browser doesn't have Flash, Silverlight or HTML5 support.

    It goes away if you refresh the browser, which isn’t such a good solution.

    Plus the submit button is disabled unless you scroll to the bottom of the rules field – even though I disabled this feature.

    So I’ve had to put notes all over the form so people can get it to work. I can’t find any alternative so please see if you can fix these issues! 🙂

    The error you are getting is a fallback from when javascript is not working correctly on the page. When javascript is working it removes that message.

    This points to a JS error on your page, this is usually a conflict caused by some JS code in a plugin or your theme.

    The first step is to check your browser console for any JS errors on that page, if there are some please post them here for review.

    A JS error would also explain the submit button issue as that is also controlled by javascript

    Hi Ben, thanks so much for getting back to me. I really appreciate all the effort you’ve put into the plugin, it’s great, I’m keen get it working on my clients site.

    Here is the link to the form. On Chrome and Safari in OSX it works fine but in Firefox it only works once you refresh the browser.

    There are no JS errors in the console as far as I can see.

    Let me know if you can see any issues, thanks

    I’ve tested the form on Browserstack using multiple versions of firefox and OS’s and the form loads correctly every time.

    As for the terms and conditions that is working as designed. The purpose of the terms and conditions is to force the user to read or at least scroll through the terms before the form can be submitted

    Hi Ben, thanks for doing that, I appreciate you help. I’m still having the same issues but I’ll leave it for now and hope we get enough submissions.

    Thanks again



    Did you get your form to work properly? It seems to work for me. I can’t get mine to work… How did you do it?

    We just ran into the same error, but it turns out the problem was with caching. We turned WP Rocket off for that specific page and the upload function worked again.
