Mixed content Warnings & Errormessages

How to check if the mixed content fixer is active

Really Simple SSL inserts a marker “data-rsssl” in the websource as a way to check if it’s working. If it it’s there the mixed content fixer is active.

Really Simple SSL requests your homepage, and parses the websource for this marker to be able to put on the configuration page a notification if the mixed content fixer is active. If the marker is not found, you get an error there. But you also get an error when your homepage could not be loaded, like when you’re behind an under construction page. In that case you might see:

The mixed content is activated, but the frontpage could not be loaded for verification.

This notice does not necessarily mean the mixed content fixer doesn’t work, it just means the page couldn’t be loaded to check that. Follow these steps to check what the problem is:

  1. Check manually if the mixed content fixer is active. If you encounter the comment, you can ignore this notice, as it apparently works. This sometimes happens when a server or security plugin blocks the plugin from opening a page on the website. How to test:
    • Right click on your website
    • click “view source”
    • Look for the mixed content fixer marker: data-rsssl=1
    • If it’s there, the mixed content fixer is active, and you’re done.
  2. If you have a caching plugin activated, the cache might still contain the websource without the marker. You can easily solve this by clearing your cache, then reload your configuration page. Really Simple SSL already clears the cache for some plugins, but not all of them.
  3. Check if you do have mixed content on your site. (Green lock in browser address bar) If you don’t have mixed content, you’re good!
  4. Another plugin conflicts with the working of the mixed content fixer. Some plugins, like Quick Cache, block the mixed content fixer. You can try deactivating your plugins to see if that helps.

    Thank you. This is helpful. I use Autoptimize to fix the above the fold content and its cache also cause this issue too.

      Hi, Can you tell me what it is that is not working?

        Hey, I also have issues… Tried almost everything from Autoptimize, SSL Insecure Content Fixer settings, HTTPS forcing, etc…
        The Content Fixer says
        “Tests completed.

        Your server can detect HTTPS normally. The recommended setting for HTTPS detection is standard WordPress function.

        Your server environment shows this:

        [FREETDSCONF] =>
        [OPENSSL_ENGINES] => /opt/bitnami/common/lib/engines
        [OPENSSL_CONF] => /opt/bitnami/common/openssl/openssl.cnf
        [SSL_CERT_FILE] => /opt/bitnami/common/openssl/certs/curl-ca-bundle.crt
        [CURL_CA_BUNDLE] => /opt/bitnami/common/openssl/certs/curl-ca-bundle.crt
        [LDAPCONF] => /opt/bitnami/common/etc/openldap/ldap.conf
        [GS_LIB] =>
        [MAGICK_HOME] =>
        [REQUEST_SCHEME] => https
        [LD_LIBRARY_PATH] => /opt/bitnami/sqlite/lib:/opt/bitnami/mysql/lib:/opt/bitnami/apache2/lib:/opt/bitnami/common/lib:/opt/bitnami/sqlite/lib:/opt/bitnami/mysql/lib:/opt/bitnami/apache2/lib:/opt/bitnami/common/lib:/opt/bitnami/varnish/lib:/opt/bitnami/varnish/lib/varnish:/opt/bitnami/varnish/lib/varnish/vmods:/opt/bitnami/sqlite/lib:/opt/bitnami/mysql/lib:/opt/bitnami/apache2/lib:/opt/bitnami/common/lib:

        but Chrome, Firefox and Safari still show “Not secure” :/

          Hi Martin,

          Could you e-mail me a link to your website (support[at]really-simple-ssl.com)? Then I will take a look.


          • Reza Aditya

            Hi Roger. I’m already doing all of the steps in my website: https://omarkatya.com/. which is use really simple ssl.

            But there is still warning like this:

            “The mixed content fixer is activated, but was not detected on the frontpage”

            Do you wanna to check it please? Thanks,,,

          • Rogier Lankhorst

            Hi Reza,
            Your site has the green lock, without mixed content errors. I can’t see the mixed content fixer marker, apparently this is blocked by another plugin. But as there are no issues, I wouldn’t worry about it.

  • Mahesh Patel

      Hi Dannie,

      Your SSL certificate is not valid. There is an SSL cert authority error. Please check your domain in ssllabs.com/ssltest

  • Nicolas Scharioth

    I’m getting the message the “The mixed content fixer is activated, but was not detected on the frontpage.”
    I’m stuck at step 4 – I tried deactivitating all the other plugins in turn, but nothing works. Any hints on what do do next?
    Can you help?
    Thanks a lot!

    • Rogier Lankhorst

      Hi Nicolas,
      If you use a caching plugin, did you clear, then deactivate? Do you have some server side caching active, like Varnish? If the mixed content fixer is not active, it’s either caching, or a plugin or theme that is blocking it.

      • Nicolas Scharioth

        Hi Rogier,
        We are not using a caching plugin (unless GZIP counts – but I deactivated it without effect).
        I suspect it might be the theme, because on another site with another theme your plugin works fine.
        What can be done about a theme problem?

        • Rogier Lankhorst

          You can test this by switching to a default theme. If it’s the theme, I’m afraid the only way to make it work would be to switch the theme.

          • Nicolas Scharioth

            Ok, I checked that and tried two other themes. No change – so it’s not the theme at least.
            I also deactivated all plugins except for Really Simple SSL and erased the browser cache. No change again.

            What else could it be?

        • Rogier Lankhorst

          I still see some references to plugins in your websource, like the WP Toolbar Removal, that could possibly cause this.

        • Rogier Lankhorst

          Could you send me an email with your debug log? rogier (at) really-simple-ssl.com

          • Nicolas Scharioth

            Hi Rogier,
            Don’t ask me why, but suddenly it is working!
            Perhaps it was sth with the cache and it just took some time to sort itself out.
            I reactivated all plugins one by one and now there’s no problem.
            Thank you for your support.

          • Rogier Lankhorst

            Great! Thanks for the update.

    “If you see this error, Really Simple SSL is not able to retrieve the websource of your homepage. It is possible your server configuration forbids this. If you find the marker data-rsssl=”1″, the mixed content fixer is working, the plugin only cannot verify this.”

    That’s what this page says above in response to the message I get from the plugin. This isn’t telling me anything useful. What does ‘the marker data-rsssl=”1″’ mean? What marker, and where?

    Site is working just fine, only issue I see is your plugin not detecting that it’s fine.

  • Rogier Lankhorst

    The data-rsssl marker is inserted in the websource as a way to check if the mixed content fixer is working. If it it’s there, the Mixed content fixer is working. I’m sorry if the text is not clear. I’ll make some improvements.

  • Rogier Lankhorst

    If you deactivate autoptimize, does it start working?

  • Terrell Boyd

    hii, recently my site ssl green paid lock not showing because my site mixed content problem showing on really simple ssl plugin.

    how to fine mixed content for my site in mobile

  • Quintin

    I have activated really simple SSL, but now none of the images on my website display.
    It looks like i need to manually re-upload each image to fix this.

    Is there another way?
    Some of my sites have thousands of images.

    Thank you.

    • Rogier Lankhorst

      Without seeing the site I can’t say much about the cause. If you have 404 or 403 results on images when the site is on SSL, this might be caused by hotlink protection. It is also possible you have photon from JetPack, which has issues with a switch to SSL.

      Another possibility is that you have located your images on a different server, without SSL certificate. Or if you use a CDN, you might need to switch the CDN url.
