Browser crashes after pressing 'Add to favourites' button


I'm having this weird issue with this plugin :

The weird part is the plugin worked like a charm about 8 hours ago :slight_smile:

Whenever I click 'add to favorite' button in these sites:

It updates "Most Favorited posts widget" but not the 'Your Favorite posts' widget. When I go back to those pages to re favorite the browser crashes after pressing the button. I tested With Chrome, Firefox, and IE they all have this problem. Plugin says it uses cookies to track favorites of non logged in users but this happens even when I logged in to the site.

I really appreciate if anyone can test this on their browser. If you could reproduce the issue please kind enough to help me resolve this issue :slight_smile:

Also please let me know if you see only a blue rectangle button in this page: without any text in it. When you hover the button text appears.
I think this causes by visited state of the button ( a, a:visited { ) How to remove visited state for this button only?


Just found out it works on my test site:
I'm not sure whether its a conflict with plugins as I haven't installed any newer one yesterday.

    Hi @chathura!

    Like you said, it's working on your test site. So I think it's worth trying to do a plugin conflict test here by deactivating all other plugins and activating it one by one to see if there's any plugin that's causing the issue? See the flowchart here:

    You can also try the method found on the "Tip: " part at the bottom of that page.

    About the "blue rectangle button", I can see the buttons fine, with texts, on that page. Please see screenshot. I'm not sure though which button you're referring too, so could you share a screenshot of it?

    Looking forward to your response!
    Thanks! :slight_smile:

      Thanks for the reply Aicee.

      I just found out the problem. Its a issue with my stupid cache plugin (WP Super Cache). I had to reconfigure the settings of that plugin as it has gone back to its original settings. Had to re run Mod_Rewrite Rules.
      Do you know what has caused this this plugin to loose my set settings? I wonder will this happen again.

      Also please confirm if the problem is solved or not in your end :slight_smile:

      About the blue button, here's a screenshot. Do you know anyway to remove the visited state of this button? You may have notice when you click on the button the color turns similar to attached screenshot.

      Thanks :slight_smile:

    Hi @chathura! :slight_smile:

    Glad to hear you found the culprit. But I have no idea how that plugin could have gone back to its default settings.

    About the visited state of the button, it's getting the default settings(color) for the visited state of all "a" tags. So, you could just set the colors that you like for it using the CSS code below:

    a.wpfp-link:visited {
      color: white;
      background-color: green;

    Let us know if you're still having any issues. Thanks! :slight_smile:
