How do I create a new wiki page?

There are several methods to create a new wiki page:

  1. Create a link from an existing page Tiki will automatically create the new (destination) page when you click the link.
  2. Create a new page by using the Quick Edit module.

You have enabled the WikiWords feature. This is a quick and easy way to create links (and create) other wiki pages.

To have a word in CaMeL CaSe not create a wiki link (even if the WikiWords feature is on), simply surround the word with two inverse parentheses.

For example: ))NotALink((
Even though the text ))NotALink(( is in CaMel CaSe, it is not a link.

How do I turn off the wiki syntax processing?

By default, Tiki will always interpret WikiSyntax, such as === for underlining and '' for italic.

To turn off wiki syntax processing, use the ~np~ syntax. See WikiSyntax for details.

You can add images (JPG, PNG, GIF, BMP) to a wiki page by using the IMG plugin wiki syntax. See Wiki-Syntax Images for details.

  • If the image file already exists on your webserver, simply include its path and filename.

Tiki requires the username admin for your administrator account. You can add a new user (with any name) and grant this use all admin permissions, but you can't rename or remove admin. Be sure to give the admin a strong password. It is best to only have one user (admin) with god level permissions.
