Call to undefined function is_utf8_charset

I’ve checked the error blog and it says:

[26-Jul-2024 07:34:26 UTC] PHP Fatal error: Uncaught Error: Call to undefined function is_utf8_charset() in /home2/latxikad/public_html/latxikadelacerveza.es/wp-includes/formatting.php:1105

Looks like the problem is with autocomplete-woocommerce-orders

I’m trying to deactivate this plugin from the back side of the web (I never operate from there, lets see

I’ve renamed the plug in but still not working

Hi latxikadelacerveza

Sorry about this issue.

If you are able to update to the latest version of WP Super Cache (1.12.4 ) and the latest version of WordPress (6.6.1) then this issue should be resolved.

Let us know how that goes.

Hello @latxikadelacerveza,

Do you have updates about this? We usually close inactive threads after one week of no activity, but we want to make sure we’re all set before marking it as solved. Thanks!
