Tinymce js文件在Wordpress中出现500错误

I have a recent WP-installation and when I want to edit a page or a post I get a 500 error message in my console.

When I check my error log it tells me the following:

[Thu Jul 30 16:01:31 2015] [error] [client some ip address] PHP Parse error:  syntax error, unexpected '",s(t),"' (T_CONSTANT_ENCAPSED_STRING) in path-to-wordpress-installation/wp-includes/js/tinymce/tinymce.min.js on line 5, referer: http://www.somedomain.com/subdirectory/wp-admin/post.php?post=7&action=edit

Could it be the problem is with the tinymce file/plugin? How can I solve this?

Kind regards,

Pim
