Two questions:

1. An unclosed tag started showing up in my post headlines and titles today.

See the numeral and end bracket at the end of each headline? I can't figure out where that's coming from. Any ideas?

2. Currently, my post headlines are in H2 on the main page, but turn into H1 on post pages. How can I make them remain in H2?

Thanks.

that looks like the end of an </h2> - what change did you just recently make?

It changes to "1>" on other pages. The only change I remember making is the one you helped me with here:

However, I undid those changes and that didn't help. I've checked and checked and was very careful to make sure I didn't change anything but what you told me. It may have happened earlier and I just can't remember what I did.

download a fresh copy of the theme, then compare the code in the function 'bfa_post_headline' in bfa_post_parts.php to see what is different

I didn't know how to compare the files, so I just replaced the old one with the new one, and voila! Problem solved. I then changed H3 to H2 again (and inserted a non-breaking space) and it's still working. So, problem solved. Thank you!

However, can you still help me with my second question?

How can I make post headlines remain in H2 on post pages, instead of changing to H1?

look at the Configure SEO bottom of page
