javascript doesn't work in new article in 5.5

[fredtantini]

With firefox 45 on debian, in core/admin/article.php, clicking on headers/display or + in thumbnail/tags does nothing.

In core/admin/top.php it seems there is an extra ".js" in <script defer src="<?php echo PLX_CORE ?>lib/pluxml.min.js.js?ver=<?php echo PLX_VERSION ?>"></script>

Thanks to the js console:
in pluxml.min.js, a semi-colon is missing line 23, char 15:
return false;}}var -> return false;}};var

But even when fixing the extra .js and the missing semicolon, the console shows a "ReferenceError: setMsg is not defined". And the thumbnails + causes a TypeError: this.opts is undefined line in pluxml.min.js line 22, char116

Just a problem with the zip on the homepage http://pluxml.org/. No problem with the source.
