Issue: Cannot Use [Category] Tag. BBCode Examples for Category tag shows: [ARG:2 UNDEFINED]

[category]

This Wiki Code can be used by clicking this button in the editor. The tag [category] is used to create links to articles in the namespace called "[ARG:2 UNDEFINED]". If the article does not exist, the link may appear in this color, and clicking the link will allow users to create the article. In regular forum posts, you can also use an optional parameter to "name" your link.
Usage	 [category]value[/category]
[category=Option]value[/category]
Example Usage	 [category]Example[/category]
[category=Example]Click here to view the category![/category]
Example Output	 [ARG:3 UNDEFINED]
[ARG:4 UNDEFINED] In wiki articles, the additional parameter is required, or the following functionality will be applied. Rather than simply linking to the category, the article will be added to the directory listing on the category's page, and the category will be added to a list of category tags at the bottom of the tagged article.
Usage	[category]value[/category]
Example Usage	[category]Example[/category]
Example Output	[ARG:5 UNDEFINED]

[image]

This Wiki Code can be used by clicking this button in the editor. The tag [image] is used to create links to articles in the namespace called "[ARG:2 UNDEFINED]". If the article does not exist, the link may appear in this color, and clicking the link will allow users to create the article. For a link, you must use an optional parameter to "name" your link.
Usage	[image=Option]value[/image]
Example Usage	[image=Example.jpg]Click here to view the page![/image]
Example Output	[ARG:3 UNDEFINED] As mentioned above, the additional parameter is required, or the following functionality will be applied. Rather than simply linking to the image, the image will be inserted into the current page. Using additional arguments in the tag's value (separated by "|"), you can also customize the appearance of the image. In any order and any combination, try experimenting by specifying:
width	in px
alignment	left, right, center
display	border, frame, none
thumbnail	thumb, thumbnail
caption	any other text
Example Usage	[image]Example.jpg|60px|right|border|thumb|some caption text[/image]
