John79You may try the following. I hope you know how to modify miniBB files.
Edit
templates/form.jsLocate the code block in the function
insertAtCursor which says
myField.focus();
myField.scrollTop = scrollTop;
return;
Change it to the following
var agt=navigator.userAgent.toLowerCase();
if(agt.indexOf("safari") != -1) window.location.href="#newreply";
else myField.focus();
myField.scrollTop = scrollTop;
return;
miniBB is the one so far board program which works with no problems on my mobile phone. So I understand developers, because they don't want to overload it with the AJAX features and so on. But this Safari fix is pretty simple... for those who know what to do :-)
