Urgent: Fix Learndash Lessons & Certificates

I'm experiencing an issue with my Learndash system where lessons are not displaying properly; only the headings are visible. Additionally, the course certificate is only displaying the course name instead of both the student's name and the completion time. I need a Learndash expert to resolve these issues swiftly and ensure everything is functioning correctly before my meeting at lunchtime.

- Critical Issues:
- Lessons not showing: This is the most urgent issue that needs to be fixed first.
- Certificate details incorrect: The certificates need to be modified to display both the student's name and the completion time.

- System Specifications: The Learndash system is a standard version with no customizations or specific plugins.

Ideal skills and experience for the job include:
- Extensive knowledge and experience with Learndash.
- Strong troubleshooting skills.
- Ability to work under pressure and meet tight deadlines.
- Good communication skills for regular updates on progress.

I want this person to check that all is okay for my meeting. If you do this - I will use you for all Learndash projects as I have no idea what Im doing.
