Hi.
Just installed new instance of NextCloud 10.0beta on Ubuntu Server 14.04 and after configuring I get Internal Server Error and the following warning in log:
PHP Warning: Expected user_input to be a string, NULL given in …/3rdparty/symfony/polyfill-php56/Php56.php on line 33
What’s also interesting is that I’ve got PHP 5.5 running there. Should it be set somehow, so that polyfill-php55 would be used instead?
