Hi toghether!

I have a big problem: after a day working normal in the admin panel, today its not loading any more. I testet it with Safari, Firefox, IE 7 + 8, and it doesn't load. I just get the image: loading... Welcome to Silverstripe and thats it.
My Firebug Console says:

Class ss.i18n not defineden_US.js...229296748 (Linie 2)
Class ss.i18n not defineden_US.js...231098970 (Linie 2)
Class is not defined
[Break on this error] FieldEditor = Class.create();
FieldEdi...229303404 (Linie 1)
Class is not defined
[Break on this error] ToolbarForm = Class.create();
tiny_mce...237164362 (Linie 1)
Behaviour is not defined
[Break on this error] Behaviour.register({

Behaviour is not defined
[Break on this error] Behaviour.register({

Behaviour is not defined
[Break on this error] Behaviour.register({
admin (Linie 723)
Behaviour is not defined
[Break on this error] Behaviour.register({
admin (Linie 740)

You can test it yourself on [url][/url]. The user ist »«, passw: »thomas«.

Thanx in advance!

Yup, there are some required javascript files that aren't loaded (as you can see in the "net" tab of firebug).
I get a 403 (permission denied) error on these assets. I guess you should have a look at the folder permissions and set them at least to readable (chmod 0644)

Edit hmm. why are these placed in /assets/ ? There's something wrong i guess. What does your .htaccess look like?

I made some changes bevor i read your comment - so I could not recognize what you wrote. I started to load the /jsparty again to the site. Now the Problem is solved, but I think it will be there again by tomorrow.
Thanks for the advice with the firebug:net feature. I almost forgot having this feature already implemented in firebug.
I will keep your comment in mind and report to you tomorrow if the problem stays on...

So, the error is back on.
My /.htaccess file is:

<Files *.ss>
Order deny,allow
Deny from all
Allow from

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{REQUEST_URI} !(\.gif)|(\.jpg)|(\.png)|(\.css)|(\.js)|(\.php)$

RewriteCond %{REQUEST_URI} ^(.*)$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* sapphire/main.php?url=%1&%{QUERY_STRING} [L]

and, the asstes folder got the permission: 0750
and, giving the *.js in the assets-folder the permission: 0640 its displaying just something, like the sitetree. but not more...

I've uploaded the .htaccess file of the installation package and now it works. but I tried this already yesterday and nothing happend...

Problem solved!

setting the right permissions in the asset-folder for the files: base.js, cmsmain.js and leftmain.js I get access to the admin panel.
But could someone tell me, why these files are in this directory??

I'm having this same problem but it's still not resolved yet. What are the correct permissions for the 3 js files? I've got them all at 755 right now, re-uploaded jsparty & still not working.

I gave them all 640. And the »assets« Folder got 750. But my Webserver need some special treatment with the file-rights.
Firebug for Firefox helped me debugging the Permission - Errors.

Good luck!
