implode(): Invalid arguments passed

[solracsf]

I've tested it with a public project, https://github.com/humhub/humhub/ and getting 500 internal server error on some assets with

implode(): Invalid arguments passed

As result, the wall feed doesn't load.

Also, IE specific files are pushed in ALL browsers, i don't know if this can be avoided:

<!--[if IE 9]>
<link href="/static/css/ie9.css" rel="stylesheet">
<![endif]-->
<!--[if lt IE 9]>
<link href="/static/css/ie.css" rel="stylesheet">
<![endif]-->

These should be pushed ONLY on respective browsers, if possible.
