Hi sauko,
I think X theme has another plugin which registered the same menu position with LearnPress (3). There are two ways to solve this problem: First, you can change the menu position of LearnPress inside learnpress.php
.
Look for this:
public function admin_menu() {
add_menu_page(
__( 'Learning Management System', 'learn_press' ),
__( 'LearnPress', 'learn_press' ),
'edit_lpr_courses',
'learn_press',
'',
'dashicons-welcome-learn-more',
3
);
Change the number ‘3’ to other number. But this method is temporary, when you update LearnPress, it will turn back to default (3).
The second solution, you can find the plugin which conflict position with LearnPress and deactivate it.
We will find a way to prevent this kind of problem soon.
Thank you so much,
Hoang
