export.php issue

[gianpaolo.cipicchia]

Hello,
I'm trying to export products from a large wordpress/woocommerce site.
Export always fails reporting: Fatal error: Maximum execution time of 60 seconds exceeded in ... (everytime different wordpress files)

I tried:

• to change dedicated server ( 16gbytes ram, 4cpu )
• to change php version (tried all versions from 5 to 7.3.10)
• to replace @set_time_limit( 1200 ) in deprecated.php line 3649,
• to change php.ini max_execution time = 1200, max_input_time = 1200 in each php version
• to put set_time_limit(1200); in wp-config
• to put php_value max_execution_time 1200 in .htaccess
• to update wordpress version to the last one
• to change db server from mysql server to mariadb
• tried Apache 2 Handler, php-cli, php-fpm installations

Same error when I launch export -> products from browser or wp-cli command:
wp export --path=/mnt/HC_Volume_2981279/wordpress/store/ --post_type=product --allow-root

(28555 products in wp_posts table)

Any idea?
Thanks in advance for your support!

An unkwnown plugin was causing the issue. Just solved, not a wordpress core problem.
Thank you
