I am using ubuntu 12.04 os, PHP 5.3. In my moodle site I was trying to upload course menu block , But its chapter section is not working. I can't change the chapter. Every time it shows error --like "
Number of chapters must be a correct number (only digits), greater than 1, less than the number of subchapters and less then the number of visible topics / weeks ! "
That error. can anyone help me ?? I desparately need this block. I posted it before but no one helped me.
