Bundle Version:

Master

Summary:

In composer.json you have: "helios-ag/fm-elfinder-php-connector": "~2.0"
and it is old for symfony2.8

Steps To Reproduce:

I tried to upload an image but ElFinder responded with: Unable to connect to the backend.
For correct this error I downloaded last version of Elfinder from this fork https://github.com/helios-ag/ElFinderPHP.

Can you fix this composer.json bug?

Also note that option "platform" under config node in composer.json make impact on packages versions that composer choose to install. i.e. platform: php: 5.3.9 will constraint elfinder-connector to ~2.4

In composer.json I set "php": "5.4" and I changed the require in:

"helios-ag/fm-elfinder-php-connector": ">=2.5",
"components/elfinder": ">=2.0"
