I got the following error while browsing courses with private, public and protected access.

[Aklilu-Mandefro]

I am using ATutor 2.2.4 version and when I try to browse a course from the public side with private, protected and public access, it displays the following error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''public' AND cat_id <>-1 AND 1 AND hide=0 ORDER BY title' at line 1
SELECT * FROM hcp_courses WHERE access ='public' AND cat_id <>-1 AND 1 AND hide=0 ORDER BY title (AT_ERROR_DB_QUERY)

// I tried a lot to fix it but I do nothing. please help me. Thank you in advance for your time to fix this issue.
