Blocks

Hello Sandor,

First of all we are very happy this block is maintained again!!!
I think it's a very good idea to sort the items and to be able to hide those one doesn't need!

Some comments:
1) Could you document how to migrate from course_menu 1.6 (Humboldt University) to 1.7 and then to 1.8? My experience: backup mdl_block and mdl_block_instance table to mdl_block_bak and mdl_block_instance. Uninstall course_menu from the administration menu, delete old course_menu folder from moodle/blocks (and language files if any from moodle/lang/en_utf8/block_course_menu.php and moodledata/lang/<language>/block_course_menu.php for the other languages). Install new course_menu (copy folder to moodle/blocks and languages to language directories, then go into administration, notifications). Run query that inserts the block where it was before in the courses, maybe even with the displaying options of your choice (order and hide items). For example, if you want the course_menu at the top left position:
INSERT INTO mdl_block_instance (blockid, pageid, pagetype, position, weight, visible, configdata)
SELECT b.id, bi.pageid, bi.pagetype, bi.position, bi.weight, bi.visible, '<configurationstring>' AS configdata 
FROM
mdl_block_instance_bak bi, mdl_block_bak bb, mdl_block b
WHERE
bi.blockid = bb.id
AND bb.name = 'course_menu'
In our case (sections, then Control Panel, GradeBook, Calendar, Show all Sections) <configurationstring> = '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'
2) I'm not quite sure what the "blog menu" is for, could you tell us?
3) I installed the course menu + on our test server and everything works fine. I also installed it locally on my computer (WAMP5 1.6.6 + moodle 1.7 or 1.8) but
a) once you add the block in a course all (1.7) or some (1.8) of the arrows for moving the blocks disappear and some blocks disappear (1.8) 
b) when you go into configuration of the course_menu it brings the errors Nasha Jiang tells (see his screenshot)
do you have any idea?
