Hi!
On three of our new websites we installed and activated today the “MainWP Child Reports” Plugin with version 2.0.5.
Sadly on one website we suddenly got the following error code:
"
Deprecated* : mainwp-child-init-subpages ist seit Version 4.0.7.1 veraltet ! Benutze stattdessen mainwp_child_init_subpages. in /homepages/43/DATABASE/htdocs/kunden/DOMAIN/wp-includes/functions.php on line *5148

"
How can we fix that?
Kind regards
