Yeah i found them too, based on your report: (line 71)
Beans uses Global Variable Variables on this code, on PHP7 are not supported anymore::
// Not supported on PHP7.
global $$set_global;
To support PHP5 and PHP7 just need to add curly braces like this:
// Separate the Variable Variables with ${$ }.
global ${$set_global};
Waiting the next update of Beans to be fixed...

Hey guys,
Thanks for reporting this, here is the fix I just pushed.
If you are keen to help with Beans development have have your name up in the contributors list, feel free to contribute directly on github as Beans is a community and open source project 😉
Happy coding,
