This should be the order your routes when you use uri as slug.
Route::get('/contacts', 'PageController#contacts')->name('contacts');
Route::post('/contact/store', 'PageController#storeContact')->name('contact.store');
Route::get('/courses', 'PageController#showCourses')->name('courses');
Route::get('coursesdetail', 'PageController#showCoursesDetail')->name('coursesdetail');
Route::get('resource', 'PageController#showResource')->name('resource');
Route::get('about', 'PageController#showAbout')->name('about');
Route::get('/{course}', 'PageController#categoryCourses')->name('course.category');
