My account is admin account So, it doesn't seems to me link a permission issue.

Please check the Events logging, and see what errors [or warnings] appear. [located near the middle of the tool bar on the main page]

Also, check the Apache [or whatever webserver you might have] logs for similar.

Let us know what you find.
