I noticed on the Grunge template that the line "Demo Content" was added to the top of each blog post in Blog View. Under Grunge Settings > Content > Page Title, the help dialog on the right says:This setting allows you to display the Page Title above all your posts on the blog page. Leaving this field empty will remove that title.
I wanted the "Demo Content" line to be gone all together, so I deleted the Page Title to empty the field and then saved changes. This removed the line, just as I had wanted, but found a problem in that after the changes were saved, the Page Title box once again refilled with "Demo Content." This proved to be quite annoying as each time I wanted to change something else in the Grunge settings, I also had to remember to once again clear the Page Title box, otherwise it would reappear on the template. I got tired of doing this so I made this change in wp_content/themes/rt_grunge_wp/html/home.php
Change:<?php if ($gantry->get('blog-page-title') != '') : ?>
To:<?php if (($gantry->get('blog-page-title') != '') and ($gantry->get('blog-page-title') != 'Demo Content')) : ?>
So, now it's set up so that nothing is displayed if Page Title is set to blank or "Demo Content" - otherwise whatever you input there will be displayed instead. It would probably make more sense if there was an on off switch for the Page Title in the settings, but this worked for me.
