Roll back to latest stable version 2.1.3 from dev-master and 'select all' will be working again.

Thanks for the report guys - this seems to have happened after the update to the source third party select 2 plugin. Will check on this.

I already found the solution, followed the error and changed the line: if (opts.length && opts[1]) to if (opts && opts.length && opts[1])
