After installing using kickstart method there's no css on the home page and the administrator page is empty! what now?

It is a bog standard Akeeba kickstart installation we use....

The Akeeba site has a very good troubleshooting section etc - also check by ftp that all folders and files are where they should be
Check you server error logs for errors etc..
Try running it again..

Have you enough disk space - you need at least 3 times the jpa file space

make sure your public_html folder has 755 permissions before you run kickstart
