You should contact the theme’s developers. (Why did you *** out the theme name?) * Thread Starter [hemasusi](https://wordpress.org/support/users/hemasusi/) * (@hemasusi) * [2 years, 5 months ago](https://wordpress.org/support/topic/php-deprecated-errors-notices-in-php-8-2/#post-17320967) * No, its not in my theme.. * We are using custom theme , theme folder name is our project name. Thats why hided that name with ***. * Moderator [Steven Stern (sterndata)](https://wordpress.org/support/users/sterndata/) * (@sterndata) * Volunteer Forum Moderator * [2 years, 5 months ago](https://wordpress.org/support/topic/php-deprecated-errors-notices-in-php-8-2/#post-17321028) * The coding deprecation issues are in your theme. * “Should i avoid these errors by disable debug mode ? or need to fix it?” * You can ignore them for now by disabling debug, but eventually, you’ll have to fix it. * Thread Starter [hemasusi](https://wordpress.org/support/users/hemasusi/) * (@hemasusi) * [2 years, 5 months ago](https://wordpress.org/support/topic/php-deprecated-errors-notices-in-php-8-2/#post-17321049) * Then what about below error, its showing in wp-includes/functions.php * [05-Jan-2024 09:25:01 UTC] PHP Notice: Error when decoding a JSON file at path/ code/wp-content/themes/****/resources: Syntax error in /code/wp-includes/functions. php on line 4601 * Moderator [Steven Stern (sterndata)](https://wordpress.org/support/users/sterndata/) * (@sterndata) * Volunteer Forum Moderator * [2 years, 5 months ago](https://wordpress.org/support/topic/php-deprecated-errors-notices-in-php-8-2/#post-17321094) * WP core is compatible with 8.2. You need to look at how you call a function in your theme. I note that you say you’re on 6.4.0. Update WP to the current version first. Maybe there was a bug fix in the last couple of point releases relevant to this. * Moderator [bcworkz](https://wordpress.org/support/users/bcworkz/) * (@bcworkz) * [2 years, 5 months ago](https://wordpress.org/support/topic/php-deprecated-errors-notices-in-php-8-2/#post-17321533) * The error in functions.php is because passing your theme’s JSON file to `json_decode()` resulted in an error. `json_decode()` is a native PHP function, not a WP function. If `json_decode()` cannot correctly parse your JSON file, it’s still an issue with your theme, not functions.php.
