Cannot modify header information

    Hi, I’ve been experiencing problems with the latest Learnpress version for updating page slugs. It is weird, where pages should be independent from Learnpress, but every time I update a page slug, I receive the following error message:

    Notice: Array to string conversion in /Applications/MAMP/htdocs/elebaires/wp-content/plugins/learnpress/inc/admin/lp-admin-functions.php on line 1243

    Warning: Cannot modify header information – headers already sent by (output started at /Applications/MAMP/htdocs/elebaires/wp-content/plugins/learnpress/inc/admin/lp-admin-functions.php:1243) in /Applications/MAMP/htdocs/elebaires/wp-includes/pluggable.php on line 1174

    I’ve checked the line in the plugin file, and it seems to me it has something to do with how Learnpress assigns IDs to posts, which seems to conflict.

    Could you please help me fix this?

    Thanks in advance.
