Invalid argument supplied for foreach() ... footer.php
After upgrading to 1.8.2 I have created 4 footer columns.
In error log I see plenty of error messages:
robime.it [Fri Dec 04 00:25:00 2015] [error] [client 188.8.131.52] PHP Warning: Invalid argument supplied for foreach() in /mnt/nfsshare/gnode004/r/o/robime.it/web/wp
-content/themes/jobroller-child/footer.php on line 7
This is the line 7: <?php foreach ( $footer_cols as $number ): ?>
What can be wrong?
