hi juan,
today i found one solution to make twitter 1.2.1 compatible with IE 8, 9, it working with IE 9 (i just have ie 9) can some body else try this and let me know that its compatible with others like ie 8
Solution: go to folder theme/twitter_bootstrap/js/item_form.js
add this line in start: try { console.log('init console... done'); } catch(e) { console = { log: function() {} } }
please let me know if its working with you and if there are any other affect some where else.
