Babel package files are missing after installation

[halftrainedharry]

Most likely it’s this bug in Babel (that hasn’t been fixed yet):

Fix "getMatrixList" processor

SOLVED::Babel and TV links not working

I think the problem is with the difference in upper-case/lower-case letters in the file getmatrixlist.class.php. (I tested it on a system that is case-insensitive, so I didn’t get an error.) Maybe try changing this line in the code to action: 'mgr/resource/getmatrixlist', (or alternatively changing the file name to getMatrixList.class.php)
