CrouchingBruin on "Header Bleeding to Right on Old Posts on Cell Phones (Customizr Pro)"

It looks like in most cases where it's not working, there's a long word in the post heading, or a subheading, that is so long that it keeps the page width wider than a cell phone width.

For example, in this post, there is this heading:
Christian Art: We Should be Innovators not Imitators
When I look at the source code for the heading, it looks like this:

<h2>Christian Art: We Should be Innovators&nbsp;not&nbsp;Imitators</h2>

Those non-breakable spaces are preventing the heading from wrapping properly. Try replacing them with just blanks and see if that fixes the problem.

In the other posts, there seems to be some longer words which, combined with the large font size of the title, do basically the same thing. For example, in this post, the word Overcomplicated seems to be keeping the page width too wide. Maybe try using a media query to reduce the font size of the post title at cell phone widths?
