It’s John Lumgair again.
After a few days of trail and error I’ve now come up with a solution. I’m not sure if it the correct answer, but it seems to work. I was told that it was probably caused by not closing a tag, maybe a div, font or a code tag. However after a lot of searching I couldn’t fix it that way.
In the style.css file I changed:
#primary h3, #primary h4, .single #primary .k2-asides h3 { /* H3 is entry headlines. H4 is comments and replyform headlines */
font-size: 2.4em;
font-weight: normal;
letter-spacing: -1px;
}
to
#primary h3, #primary h4, .single #primary .k2-asides h3 { /* H3 is entry headlines. H4 is comments and replyform headlines */
font-size: 22.4px;
font-weight: normal;
letter-spacing: -1px;
}
I’m not sure why that worked but I hope it can help others if they encounter the same problem.
