Multisite Issue

Hello, I am using the plugin for a multisite store.

For main website is working well, but for second store I cannot add any license because when I search product or order is shows: The results could not be loaded.

I also notice that there is not tab : License Manager in product edit in wp-admin.

Debug says that: [22-Apr-2025 09:29:02 UTC] PHP Notice: Function wp_is_block_theme was called <strong>incorrectly</strong>. This function should not be called before the theme directory is registered. Please see <a href=”https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/”>Debugging in WordPress</a> for more information. (This message was added in version 6.8.0.) in html/wp-includes/functions.php on line 6121

I tried to change themes, I tried to disable plugins, still have this error.
