forum posts have inappropriate, invisible line breaks : <p>I cannot for the life of me figure out why, when people post on my php forum (called Just A Forum, from codecanyon [unsupported]), the posts tend to look like this:</p>

<p><a href="https://i.stack.imgur.com/yIy11.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yIy11.png" alt="forum post sample screenshot"></a></p>

<p>Inspecting with chrome dev tools, the text looks fine and I don't see any evidence of line-breaks. I've played around with the textarea width, making it match the text container width, but that doesn't seem to help. Neither did making sure the padding also matches, the font, etc.</p>

<p>Rather than post a bunch of CSS that could turn out to be irrelevant, I guess I'll wait for some instruction. I really just would like a clue as to where I should look, things I could try. I don't even know where to begin, with this. </p>
