PHP Warning: Undefined array key 0

Support
#1

On top of my site this message appears:
PHP Warning: Undefined array key 0 in /srv/home/64613-duomusacom/domains/duomusa.com/htdocs/www/wp-content/plugins/cornerstone/includes/classes/styling/class-font-manager.php on line 196.

Can someone tell me how to fix this?

Hey @hilbertgeerling,

Thanks for reaching out!

You have nothing worry with the PHP notice and PHP warnings because it doesn’t affect any functionality for you website.

To disable the warning on your website by following this link disable PHP warning notices.

Hope that helps.

Thanks. But this looks like ‘killing the warning light’.
Is it not better to repair the actual error. What did I do wrong to get this message?

Also… I did the change in de config.php file, but the error message still appears…
the site is: www.duomusa.com

Hi @hilbertgeerling,

Regretfully, the site URL is not accessible from multiple locations and the devices, it shows a DNS_PROBE_FINISHED_NXDOMAIN error. This could be related to security that blocks certain countries, I recommend checking this with your hosting provider as well.

Thanks

For your information:

I found out that the php I was using was the new version 8.
This version is more strict than the previous ones.

So installing PHP 7.4 fixed the issue.
The php warning on the top of my site page disappeared.
