Hi there,
I have like thousands of lines in error.log file about this function.
PHP Deprecated: Constant FILTER_SANITIZE_STRING is deprecated in /wordpress/mu-plugins/atomic-platform.php on line 559
I have checked with hosting and they told me that it is related with my theme.
I have searched for FILTER_SANITIZE_STRING in theme files and find below results.
generatepress\inc\meta-box.php (4 hits)
Line 231: $sidebar_layout_value = filter_input( INPUT_POST, $sidebar_layout_key, FILTER_SANITIZE_STRING );
Line 240: $footer_widget_value = filter_input( INPUT_POST, $footer_widget_key, FILTER_SANITIZE_STRING );

Another plugin solved it like below according to their comment.
/*
* Replacer for FILTER_SANITIZE_STRING deprecated with PHP 8.1
*/
public static function filter_string_polyfill(string $string): string {
$str = preg_replace('/\x00|<[^>]*>?/', '', $string);
return str_replace(["'", '"'], [''', '"'], $str);
}
// end of filter_string_polyfill()Hi there,
Can you confirm that you are using the latest versions of the theme and premium plugin?
https://docs.generatepress.com/article/generatepress-and-gp-premium/
The initial error doesn't look like it's related to the theme.
Can you disable all non-GP plugins to test?
Let me know :)
Hi Leo,
Yes both GP and GPP are latest versions.
FILTER_SANITIZE_STRING is deprecated and this file still has it. generatepress\inc\meta-box.php
I don't see any point to disable others plugins and check again.
Hi there,
thanks for reporting that we will take a look at getting that replaced.
