Hi @funtrick!
The problem on your website is, that you have a plugin, which replaces hex color codes with urls for some reason. So where we have this inline CSS code:
background-color:#1877F2;
the code on your website turns it into:
background-color:<a href="https://funiqskills.com/social/tag/1877F2/" rel="nofollow" class="hashtag">#1877F2</a>;"
Since your https://funiqskills.com/social/ page displays BuddyPress, I assume the source of the issue will be within their settings. I suggest temporarily turning off BuddyPress, just to confirm the source of the problem. If you see that they are creating the issue, turn them back on, and check out their settings to see if you can find something related to “creating tag urls”, as they are probably trying to do that.
If you couldn’t find their setting, you should try to contact BuddyPress developers and ask them about this. Although even if you find their settings, you could still try to contact them, as this is a bug in their code what they should fix.
If the source of the problem doesn’t seems to be BuddyPress, you could try to use Health Check & Troubleshooting plugin similarly as you see at another plugin of ours:
https://smartslider.helpscoutdocs.com/article/2006-how-to-use-health-check-troubleshooting-plugin
to find the source of the issue. Just at Step 2, press “Troubleshoot” at Nextend Social Login, and at Step 3 visit your https://funiqskills.com/payment-settings/ page. If you find the plugin/theme causing the issue, I suggest the same here, check out the settings and contact the developers if you cannot find it or if you want this to get fixed.
