Is it case that ElFinder#upload($args)'s $args['upload'] is ""?

[helloooideeeeea]

resolved it!
ElFinder 's source was old.
execute the following command, I resolved it.
$ composer update --with-dependencies helios-ag/fm-elfinder-bundle

Hi, i exactly the same issue (CRITICAL - Uncaught PHP Exception Symfony\Component\Debug\Exception\ContextErrorException: "Notice: Undefined variable: header" at H:\wamp2\www\appar\vendor\helios-ag\fm-elfinder-php-connector\src\ElFinder.php line 1543 )

I tried to update package with the command line "composer update --with-dependencies helios-ag/fm-elfinder-bundle" but composer said "Nothing to install or update".

I can't upload file on server ,other functionnalities works (browser, use picture and so on) but unable to upload, i'm stuck !

Please help

Hi @salamichel
What about platform setting in your composer.json? Also you can explicitly set connector library to fetch with

composer require helios-ag/fm-elfinder-php-connector: dev-master 

or

composer require helios-ag/fm-elfinder-php-connector: 2.5.1

Hi , thank for your reply, i tried both command

Could not find package 2.5.1 at any version for your minimum-stability (stable). Check the package spelling or your minimum-stability

This

"platform": {
"php": "5.3.9"

prevents installing 2.5.1, please leverage php version to at least 5.4
