Hello,
Testing on the latest QACMS 2.0 tree, I noticed that, because of CakePHP 3.1.0 release, it is updated too to that version.
So far so good, but CakePHP strongly protest about some deprecated functions usage, and looking to CakePHP 3.1.0 Porting Guide, there are maybe possible another small hidden issues generated by the slightly different implementations.
Sure, the developers can choose to port QACMS into CakePHP 3.1.0, and probably is the best solution, but maybe it's better to follow the CakePHP 3.0.x releases until the QACMS reach a good stability and/or a final stable release.
To implement that
CakePHP 3.0.x releases following, I suggest a very small patch against
Website's
composer.json (file attached).
All the best!
