Hardcoded Lorem Ipsum text in TemplateMonster template

[KsR01]

I have a new Zen-Cart set up, installed via Softaculous, no plugins or addons. It is set up with a Template Monster Template that came with some sample products. I've had decent success making changes as I go, but there's one thing that stymies me - the stupid Lorem Ipsum nonsense on the front page under the Welcome banner.

I've looked up a few different fixes, and they all seem to point to editing the index.php file in /public_html/store/includes/languages/english/theme718 but when I edit the lorem ipsum text in notepad, save and re-upload, the site goes blank white. I'm only editing the lorem ipsum text, but even the smallest change wrecks the site's ability to load, so I've had to replace the index.php file from the original every time. I'm aware that Template Monster doesn't get a lot of love here, but this template is meeting my needs - with the exception that the obvious solution is not working. Any ideas? This should be a simple fix, I thought. I've looked for the file in PHPmyAdmin, but I don't see it in the database.
