Registration with PHP7.2 not working

hi jaques,

i test the registration on php7.2

i dont have enabled rapid registration, so the user have 4 steps to create their profile.

at step4, the user can optionally change his username.
now if the user press “ok” or “next” to finish his userprofile, then only appears a blank white page and nothing happens.

if i change to php 7.0 all working fine and the user can finsih his profile, but not with php 7.2

i tested already on two different pages and webhosts.

in debug mode this:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function wc_maybe_store_user_agent(), 1 passed in /home/transgen/public_html/wp-includes/class-wp-hook.php on line 286 and exactly 2 expected in /home/transgen/public_html/wp-content/plugins/woocommerce/includes/wc-user-functions.php:679 Stack trace: #0 /home/transgen/public_html/wp-includes/class-wp-hook.php(286): wc_maybe_store_user_agent(‘gulle’) #1 /home/transgen/public_html/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array) #2 /home/transgen/public_html/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /home/transgen/public_html/wp-content/plugins/rencontre/rencontre.php(992): do_action(‘wp_login’, ‘gulle’) #4 /home/transgen/public_html/wp-content/plugins/rencontre/rencontre.php(362): Rencontre::rencIniUser() #5 /home/transgen/public_html/wp-includes/class-wp-hook.php(286): Rencontre->rencwidget(”) #6 /home/transgen/public_html/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array) #7 /home/transgen/public_ht in /home/transgen/public_html/wp-content/plugins/woocommerce/includes/wc-user-functions.php on line 679
