I have two theme in my wordpress 3.0 When l try to change my template in theme management area, when l click change theme, theme should opn in a pop-up with try screen and there should be a link on tops to apply or cancell. but when l click it opens in same window without pop-up and default theme comes like its index.php

How can l solve this issuee?
Have you tried:
- deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
- switching to the default theme to rule out any theme-specific problems?
- resetting the plugins folder by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.
- re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress?
- increasing the available memory?
