I think I stumbled upon a bug.
Normal url field in a blueprint, worked as expected for the past 2 years.
Today I got this error for the first time
The site I was trying to post on my gallery is this one http://special—offer.com/ but looks like this url is something the url field doesn’t like.
@texnixe can you doble check if this is really the case and let me know if you want me to open a bug in the panel repo.
