 * Hello,
 * As of today, I am seeing the following error in the error.log:
 * [21-May-2021 06:11:48 UTC] PHP Warning: Invalid argument supplied for foreach()
   in /home/*******/jbeducation.co.za/wp-content/plugins/all-in-one-seo-pack/app/
   Common/Traits/Options.php on line
 * I also saw that my site was throwing 503 Service Unavailable errors. So I deactivated
   the AIO plugin and the site comes back to normal. I reactivate the plugin, the
   errors return.
 * So I enabled Debugging and found nothing more is returned. Still only 503 errors.
   Log file is also the same warning.
 * I am running Latest WordPress and PHP 7.4
 * I would appreciate it if support would assist otherwise I will need to use Yoast.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2F503-errors-and-php-warning%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Sure, I would have done that first but figured I had to pay for the support. 
   So I logged it here instead.
 * I will open a ticket there as you requested 🙂

 * Hi [@bluesteam](https://wordpress.org/support/users/bluesteam/),
 * We have now released version 4.1.1.1 of All in One SEO which fixes the issue 
   with updating the plugin affecting some users.
 * Please update to version 4.1.1.1 and let us know if you still have any problems.

 * [@bluesteam](https://wordpress.org/support/users/bluesteam/) Awesome, glad to
   hear it! It was a rather niche issue so that’s why it didn’t come up during our
   testing.
