Form script syntax error
Does anyone have experience with hostiso.com? There the sending of the form does not work. Hostiso thinks that there is a syntax error (see screenshot line 7). For example I have included the form on this page (at the bottom of the page) https://outperform.academy/seminar-mitarbeitergespraeche/
What surprises me: I have tested the site also on hosteurope.de and everything works there without any problems. I also downloaded and tested this script (https://css-tricks.com/sending-nice-html-email-with-php/) with exactly the same result: It does not work on hostiso and on hosteurope it works without problems.
Does anybody have an idea?!
