https://www.zeilschoolhetnieuwemeer.nl/contact This link also had problems after update that I wanted to fix (picture of location (google maps) did not work). Plus lots of junk because of contactform. Installing catch Decided to throw page in de trash for a split second. Regret, so restored it, but I cannot get rid of the __trashed part at the end. Chaning the permalink in page and publish does not work. https://www.zeilschoolhetnieuwemeer.nl/contact__trashed/
