you have a alternative, if you dont want to upgrade the old wb - stop the project
or you build a own server (at home) and work there till the end of the project with old php 5.4 and wb
the fix for the problems with all the old stuff is the latest version.
what do you think, why is the latest bakery not your used version 1.73?
is it's possible, that something not work with newer php-version and because of this, the autor builds a upgrade?
php 5.4 is outdated since sep 2015
- see here other unsupported version of php -> http://php.net/eol.php
it's recommended, to use the latest wb-version in combination with the latest php-version, otherwhise, you run from one problem to another
