Remove Bold Link Underline

First, install a plugin like Simple Custom CSS so you can add Custom CSS code to your site without modifying your theme.

Then, add the following code to remove it:

.entry-content a { border-bottom: 0; }

In CSS-speak, it’s technically a “border” and not an “underline” underneath the links right now.

Also, it’s worth mentioning that the color of links and color of normal text is pretty similar. It would be difficult for your visitors to differentiate links without any underline at all.

If you’d rather have a thin underline underneath links, use this instead:

.entry-content a { border-bottom: 0; text-decoration: underline; }

Personally, I think this is the best of both worlds. You get rid of the super thick border (I agree it looks a bit out of place), but still have a nice thin border to differentiate the links from normal content.

Hope this helps!
