I see, it looks like the issue isn’t caused by the theme, it’s coming from the text and code you pasted in your content area. If you look at the source code it shows that you added this in when you pasted the text. When pasting things into WordPress you have to make sure you’re just pasting text, otherwise, if you copy/paste from something like Microsoft Word for example, it will add in a bunch of code from Microsoft that isn’t needed for your site.
Here is the link to your page source – view-source:http://www.copyandartinaction.com/online-masterclasses/ …..or just right click and view page source to see that it’s all there.
You’re going to need to go into your content/page editor and click the “Code” tab so it shows all of the hidden code that was added after you copy/pasted it in. Once you’re in there, then you can erase what you don’t need.
Where did you copy/past from?
