Error file put contents Exclusive locks are not supported for this stream

Question

Issue with session storage

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

 Indicating to remove the reference to

$lock on line 74 in Filesystem.php

Seems like a quick fix which will lead to other issues down the road...

How do I take care of the root cause?

Hello,

After update do:

chmod -R gu+w storage

chmod -R guo+w storage

php artisan cache:clear

Hope it works!!

Thank You!!
