I'm trying to install the "attendance" plugin (both the module and the block) for the first time, but the documentation available on the Internet is a big confusing.
First there seem to have two modules. One is a "core" module that is documented in the http://docs.moodle.org/23/en/Attendance_module#Installation
This module, according to the doc, need to be installed to /mod/attforblock
Then there is another one mentioned in the plugin database, which can be found at
This one, according to the readme file, need to be installed into /mod/attendance
Then there is also a "block" piece, which seems to be optional (according to this doc), and need to be placed in /block/attendance
So if I have all three pieces in place, I would get this error message. Anyone know what's wrong? Thanks!
