Remository

If you have problems that relate to reading or writing files in the file system, or accessing directories in the file system, this may be to do with permissions. Bear in mind that hosting often creates a situation where your CMS (and therefore Remository) is running as a different user from you as a FTP user. So it does not follow that because you can do something via FTP, Remository should be able to do the same thing.

My consistent recommendation when running any advanced system such as a CMS is to use hosting that supports some kind of PHP-suexec. This makes the CMS user the same as the site owner, which allows things to be simpler and less troublesome. Unfortunately, most hosting does not work this way.

For a full discussion of these issues, please read the paper "Permissions and Hosting".
