Thank you! We removed flowplayer, but there is still the problem when running on php7.
I played around with the homepage and found out that after removing the
tag from our main template, it is running on php7. But because that can't be a satisfying solution, I tried to change the code from our start page. Even when I use
in the corresponding resource, the problem still exists.
We use a package called "Flexibility 4", could this one cause the problem or is this just written in HTML and JS (no PHP)?
Another package which seems to be quite old is "phpThumbsUp". It has PHP 5.3.x as minimum requirement.
I hope you can help me!
