Error Page when going to category

Hi! New to Squarespace. I recently began using categories to organize my blogs. So far have 2 categories - 1 appears to be working (skill sharing) when I click on the category from my main blog page however the other doesn't (LGBTQ health care - when I click the category it takes me to error page). https://www.rdlmft.com/blog Thanks for any help!

Try edit category name >> Check to see if you used any blank space after "Q", because I see a strange character appears in category url

ok thank you I had a "+" which made the site unhappy, removed and it works now! thanks again
