v6.4.4

Fixed

📚 Lesson Preparation — Members can finally see their assigned lessons

• Members saw "لا توجد دروس" even when correctly assigned. get_lessons() built its prepared-statement parameters in WHERE-first order, but the access INNER JOIN (… WHERE user_id = %d) subquery appears before the WHERE l.status = %s clause in the SQL text. $wpdb->prepare() binds placeholders left-to-right, so for a member the user ID and status string were swapped: user_id was bound to "published" (→ 0, no such user) and status to the numeric user ID (no such status) — so the query matched nothing. The join params are now merged ahead of the WHERE params so binding order matches the SQL text.
• Admins were unaffected (their preview path adds no access join), which is why this stayed hidden until per-member access actually started saving in 6.4.2. Lessons must still be published (not draft) to appear to members.
