Results and highlight showing HTML ciode

Bold support would probably be better at providing answers to this question. I took a look at the Bold Builder plugin, which is free, but I think this problem is stemming from your theme, which is a Premium product. I can’t see what your theme is doing on the search results page, but it looks like it’s escaping the HTML code instead of displaying it directly.

Please ask the Bold support how to fix that. They should know how you can get the excerpts to be unescaped, or they will tell you it’s not possible, in which case you need to disable the Relevanssi custom excerpts.
