Mir geht es genau so. 
Wie bei meinem Vorgänger scheint plötzlich das komplette Javascript im Backend nicht zu funktionieren. Allerdings nicht anch einem Update, sondern einfach so, ganz plötzlich.
Ich habe nun auch die Mootools Pfade verändert und das Umschreiben der URLS wieder deaktiviert. Die .htaccess Datei ist auch aktiviert.
Vielleicht ist noch ein anderer Pfad nicht korrekt?
Das hier ist meine Javascript:
PHP-Code:
<script type="text/javascript" src="plugins/tablesort/js/tablesort.js"></script>
<script type="text/javascript" src="plugins/mootools/mootools-core.js"></script>
<script type="text/javascript" src="plugins/mootools/mootools-more.js"></script>
<script type="text/javascript" src="plugins/slimbox/js/slimbox.js"></script>
<script type="text/javascript" src="plugins/ufo/ufo.js"></script>
<link rel="stylesheet" href="plugins/slimbox/css/slimbox.css" type="text/css" media="screen" />
<link rel="stylesheet" href="plugins/tablesort/css/tablesort.css" type="text/css" media="screen" />
Und dies meine .htaccess Datei
Code:

<IfModule mod_rewrite.c>
RewriteEngine On
##
# Rewrite base
#
# Set the RewriteBase if your TYPOlight installation is in a subdirectoy and
# the rewrite rules are not working properly. Usage examples:
#
# RewriteBase /typolight-2.8.0
# RewriteBase /path/to/typolight
#
# Add your own RewriteBase after this comment.
##
##
# Malicious requests
#
# TYPOlight usually does not pass absolute URLs via GET, therefore the
# following rules block all requests that try to pass a URL or the /etc/
# directory as parameter.
##
RewriteCond %{REQUEST_URI} (ftp|https?):|/etc/ [NC,OR]
RewriteCond %{QUERY_STRING} (ftp|https?):|/etc/ [NC]
RewriteRule .* - [F,L]
##
# Compressed .js and .css files
#
# Most of the JavaScript and CSS files used in TYPOlight are also available
# as compressed .gz version, which requires less bandwidth and optimizes the
# page loading time. The following rules load these compressed ressources.
##
AddEncoding gzip .gz
<FilesMatch "\.js\.gz$">
AddType "text/javascript" .gz
</FilesMatch>
<FilesMatch "\.css\.gz$">
AddType "text/css" .gz
</FilesMatch>
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{REQUEST_FILENAME} \.(js|css)$
RewriteCond %{REQUEST_FILENAME}.gz -f
RewriteRule ^(.*)$ $1.gz [QSA,L]
##
# Static ressources
#
# Do not rewrite requests for static files or folders such as style sheets,
# images, movies or text documents.
##
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
##
# TYPOlight URLs
#
# By default, TYPOlight adds ".html" to the generated URLs to simulate static
# HTML documents. If you change the URL suffix in the back end settings, make
# sure to change it here accordingly!
#
# RewriteRule .*\.html$ index.php [L] # URL suffix .html
# RewriteRule .* index.php [L] # No URL suffix
# RewriteRule .*\.txt$ index.php [L] # URL suffix .txt
#
# If you are using mod_cache, it is recommended to use the RewriteRule below,
# which adds the query string to the internal URL:
#
# RewriteRule (.*\.html)$ index.php/$1 [L]
#
# Note that not all environments support mod_rewrite and mod_cache!
##
RewriteRule .*\.html$ index.php [L]
</IfModule>
AddType x-mapp-php5 .php
AddHandler x-mapp-php5 .php
Mir ist aufgefallen, dass es im template Bereich allerdings eine weitere .htaccess mit dem Inhalt "order deny,allow
deny from all" gibt. Aber ich vermute, das tut nichts zur Sache.
Es wäre schön, wenn mal jemand drüber schaun könnte, da ich mich mit der Materie noch gar nicht auskenne
