This is still an issue. You can see the live version on http://youfront.dk.
If you look in the sourcecode, the first error should be on line 133.
Hello.
I’m not familiar with the WordPress theme Tesseract, but its simpel CSS.
.CSS-selector {
color: black !important;
}
The !important is added so it overrides any attribute of color already set in that CSS selector.
If you would provide a link to your site, i could review it, and send you the correct CSS code.
