Sounds like you've got it fixed! Good!
I've almost learned my lesson about 3rd party add-ons ... but like you, I keep hoping I'll acquire enough knowledge to fix 'em. :| Is that version of joomdle compat with version 2.2.x?
Have, myself, been tinkering with Joomla as backend for some things in Moodle - without any 3rd party add-on. Yes, it's limited ... doesn't have SSO, etc. but maybe that's good! ;)
Moodle 2 has a mobile theme. Is there something 'moodle2mobile' does that the built in mobile theme doesn't do?
Might I suggest a more 'conservative' approach? Rather than adding 3 themes, a mod, etc. all at once ... how about a little at a time? As they say, 'Rome wasn't built in a day!' And it sure is painful when 'Rome burns' before it's time! ;)
