It still doesn’t work. When I search for ‘H&M’ now, I still don’t get search results. If I look at the url of the search result I see: http://www.stylediscount.nl/?s=h%26m, so there might still be some error in that code?
Thanks for your response Mikko! Could you maybe tell me where to place this exactly in the functions.php? I copy-pasted it after the last rule that was in there and it broke my site. I placed back the back up file but now I don’t want to try again and paste it somewhere else.
Thanks in advance!
