WP Adding Strange Code to End of Permalink URLs

It’s a rogue plugin. Try deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin.

Thank you esmi. I deactivated all plugins, but it still persists. What’s weird is the actual hyperlinks show correctly, it is only when you go to the article/page it then adds the code at the end.

It’s definitely a plugin issue. I’ve seen it a number of times before. Try resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

Thanks esmi! OK, found out what it was. I had manually put in the addthis code and this was the error. Here was the code in my single.php file minus my id:

<div class="addthis_toolbox addthis_default_style ">
<a class="addthis_button_tweet"></a>
<a class="addthis_button_google_plusone" g:plusone:size="medium"></a>
<a class="addthis_counter addthis_pill_style"></a>
<a class="addthis_button_facebook_like" fb:like:layout="button_count"></a>
</div>
<script type="text/javascript">var addthis_config = {"data_track_addressbar":true};</script>
<script type="text/javascript" src="https://s7.addthis.com/js/250/addthis_widget.js#pubid="></script>
</div>

Thinking it had to do with the ‘data_track_addressbar’ feature they have (where you can see when someone copies and pastes the URL instead of using a share button. Thank you again for your help, you helped me look in the right direction ??

The other way to fix (courtesy of the AddThis tech team):

That code is added by address bar tracking. You can disable it by going to the advanced tab of the AddThis settings page and unchecking the Track address bar shares checkbox: https://i.imgur.com/SPuV4.png
