Attendance (plugin)

First of I need to express my thourough delight the module, exactly what is needed. Now the "however".

After installation I received errors when accessing content whithin the frame blocks. I therefore went ahead and deleted the attendance block again. Having removed everything I now can no longer access the edit mode of a course.

I'm using moodle 1.8+ and the lates release from Dmitry's version of the attendance block (v1.0.9).

Any solutions, ideas or redirections to save me reinstalling the entire moodle package would be highly appreciated.

Cheers,
Peter
