* the wiki.cfg file (located in the ConfigDir directory) * The top Context page (also Top:Context)

# the WikiConfigFile wiki.cfg, which is located in the ConfigDir directory # the top Context page, also referenced as Top:Context (see TopContextPage)

The wiki.cfg file is read before the top Context page, so the options of the Context page may overwrite the options defined in wiki.cfg.

1. the WikiConfigFile wiki.cfg, which is located in the ConfigDir directory
2. the top Context page, also referenced as Top:Context (see TopContextPage)

There are some Variables that can not be redefined in ContextPages:

Variable %VarLockedHash: AllowEdit => n ContextPageName => n CookieName => n DataDir => n DateLimit => n DefaultRights => n ExecutablesDir => n GlobalDir => n PageLimit => n ScriptFile => n TemplateInsertPassList => n UploadUserQuotaMax => n UploadWikiQuota => n UserName => n WebDir => n WikiBase => n WikiCharset => n

If these variables occur in ContextPages, they are just ignored. There is no error message when you use them.

They are blocked for redefinition becauseof :

• technical reasons: e. g. the CookieName must not change because otherwise the user reference to his preferences data is lost.
• security reasons: e. g. a changeable UserName could make you an admin
• logical reasons: e. g. DateLimit and PageLimit are limits given by the ProWikiProvider to the wiki owner
