PHP Warning in class-schedule.php

[pdewouters]

An intercom user reported the following error

Warning: Invalid argument supplied for foreach() in /var/www/web796/html/www/wp-content/plugins/backupwordpress/classes/class-schedule.php on line 930

I've asked the OP for a var_dump of $haystack as I'd like to understand the contents of the arg that is being passed to the foreach.

Regardless though there are a couple of things we should do to avoid this situation:

• in L930 check that glob( $haystack . '/*', GLOB_ONLYDIR | GLOB_NOSORT ) returns a valid array before trying to foreach it.
• in L885 use wp_upload_dir to get the path to the uploads directory (and ensure it actually exists etc.).

thanks for reporting this. Totally my fault forgetting to use wp_upload_dir
