php – WordPress Importer Name to undefined operate set_time_limit()

I’m attempting to import my media library through the wordpress importer, however I hold operating into this error, which seemingly lacks a proof:

root@check:~# grep -R "max_execution_time" /and so on/php/8.1/
/and so on/php/8.1/cgi/php.ini:max_execution_time = 900
/and so on/php/8.1/fpm/php.ini:max_execution_time = 900
/and so on/php/8.1/fpm/pool.d/1648278293221077.conf:php_value[max_execution_time] = 900
/and so on/php/8.1/fpm/pool.d/www.conf:; be killed. This selection must be used when the 'max_execution_time' ini choice
/and so on/php/8.1/fpm/pool.d/166643563141647.conf:php_value[max_execution_time] = 900
/and so on/php/8.1/cli/php.ini:max_execution_time = 900
/and so on/php/8.1/apache2/php.ini:max_execution_time = 900

Additionally, my `wp-config.php` has `ini_set ( 'max_execution_time', 900);`

So at this level, I'm confused...  Anybody have any concepts?
