After upgrading to PHP 7 I started getting "storage folder isn't writable by PHP" errors

Question

I just recently upgraded to PHP 7. The browser is now showing following error

/home/xxx/craft/storage isn't writable by PHP. Please fix that

Have not changed any permissions on any of the folders. How to fix this problem?

Answer 1

Try resetting the permissions of the storage folder:

(It's possible that PHP was running with higher-than-default permissions in the previous setup, in which case everything may have worked even if you hadn't explicitly made the storage folder writable.)
