error on frontend and admin page

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client was experiencing a deprecation notice related to WPML when trying to update their website. The notice was as follows:

Deprecated: mb_convert_encoding(): Handling HTML entities via mbstring is deprecated; use htmlspecialchars, htmlentities, or mb_encode_numericentity/mb_decode_numericentity instead in /****/sitepress-multilingual-cms/addons/wpml-page-builders/classes/Integrations/Gutenberg/strings-in-block/dom-handler/dom-handle.php on line 32

Solution:
We recommended that the client disable debug mode in WordPress to prevent these warnings from being displayed to visitors. This can be done by editing the wp-config.php file and ensuring it contains the following line:

define( 'WP_DEBUG_DISPLAY', false );

We advised the client to try this solution after taking a backup of their website and to share their feedback with us.

Please note that this solution might be irrelevant due to it being outdated or not applicable to your case. If this is the case, we highly recommend checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket with us.

Bigul WPML Supporter since 01/2013 Languages: English (English ) Timezone: Europe/Vienna (GMT+02:00)	Hi Arwut, Thank you for the updates. The following notice is related to WPML. However, it appears to be a compatibility issue, and this deprecation notice has not been reported in the past. Deprecated: mb_convert_encoding(): Handling HTML entities via mbstring is deprecated; use htmlspecialchars, htmlentities, or mb_encode_numericentity/mb_decode_numericentity instead in /****/sitepress-multilingual-cms/addons/wpml-page-builders/classes/Integrations/Gutenberg/strings-in-block/dom-handler/dom-handle.php on line 32 This notice will not break your site or its functionality. To avoid displaying these unwanted warnings and errors to your visitors, it's best to disable debug mode in WordPress. This is a recommended practice to ensure peace of mind. To do so, edit your wp-config.php file and ensure it includes the following line. Please give it a try after a backup and share your feedback with us. define( 'WP_DEBUG_DISPLAY', false ); -- Thanks!
