Thank you for the proper details, it helped me a lot!
I was not able to log-in to the back-end, the login page redirected to the non-dev domain, however I was able to fix the issue via FTP.
There was some unclosed HTML tags within result content, causing the problem. I have added an extra line to the taxonomy search file to handle those tags, now it should display correctly.
I will make sure to include this fix in the upcoming release, so you won't have to worry about it again.Best,
