Hello, i've problems after installation. When i try go to site.com/admin im getting 500 internal error. But when i copy files from /admin catalog to other place it's working. Some1 know why i've 500 internal on /admin catalog? i've 777 chmod etc.

Sounds like a corrupted install.
Try reinstalling again.

Your server may reserve that space for something else. Ask your web host if there is any reason why you might get a 500 error when accessing the /admin directory.

If you have other software installed on your site that is up a directory from Pligg, that may be interfering with the /admin directory. Check for .htaccess files outside of Pligg that may be messing with the admin folder.
