Session storage not working with my Laravel 5. Used it for a month without problems. But since latest upload to web server I get the following response on every page.
ErrorException in Filesystem.php line 74:
file_put_contents(): Exclusive locks are not supported for this stream
Many posts on the internet are indicating to remove the reference to
$lock on line 74 in Filesystem.php
How do I take care of the root cause?
