There are a few things you should have in mind when you choose a web hosting environment for Joomla!™ CMS.

1. You want Joomla to have write permissions for the Joomla files and directories. Many web hosts gives you problems here, with Joomla giving messages like “Failed to move file”, or “A file permissions error has occurred.” In such situation, you can use an FTP client to CMOD the files and folders that has to be writable for the web server, but that can be a very time-consuming task. In Joomla 1.5, some of these problems have been solved with the helpful FTP layer function. However, why not choose a web hosting service that gives write permissions to Joomla from start?
2. The php-setting 'Safe_mode' should be OFF.
3. If you want to use Search Engine Friendly URL:s for you Joomla website, which you probably do, you need mod_rewrite to be enabled in Apache.
4. For security reasons, Register_globals should be OFF.
5. For security reasons, choose a web host with php5.

With ServeU.net web hosting, Joomla runs smooth from start, and you can change any php-setting with the php.ini file located in the /sys/ folder accessible via the File Manager in the web hosting control panel.
