Hi Salah, and welcome to the E-Learning Heroes community!
I'm sorry to hear that you're running into this issue when trying to export your course to PDF, but I'm happy to help troubleshoot!
- When are you seeing the error message? Is this happening after you select Export, then PDF?
- If possible, can you share a screenshot or share the exact error message?
- Is this happening with one specific course or multiple courses? If it's only this course, have you tried duplicating the course and exporting it again?
If you need further assistance, please let me know here or privately in a support case!
