How do I make my tumblr URL support redirect links?

[Hoda]

I'm really happy with my theme and I don't want to change it but the only thing is I can't make redirect links for example if I wanted to make a link that takes you to all the pics of food I posted on a personal blog. It always says "your theme does not support redirect links" how do I change my URL to fix that?

Thanks

Click “Add a Page.”
Type a Page URL after the slash (/). For example, if you’re redirecting to Twitter, you could type /mytwitter. If you’re redirecting to Facebook, you could use /myfacebook.
Change the Page Type from Standard Layout to Redirect.
Type or paste the web address that the Page will redirect to.
Check the box that says “Show a link to this page” and give the Page a title in the field next to the checkbox (e.g. My Twitter or My Facebook).
Click “Create page.”
Another frequently-asked question we get is “How can I make a link that takes you to all of my posts on a certain topic? Like ‘Personal’ or ‘My Face’ or ‘My Poetry’?” No problem! You can use a Page along with post tags to organize common posts.

The first thing you need to do is make sure that all the posts you want to appear on that page are tagged appropriately, i.e. with the tag “poem” or whatever. Then, you will follow instructions very similar to the ones above:

Click “Add a Page.”
Type a Page URL after the slash (/). For example, /mytag, but replace “my tag” with the tag you want to use.
Change the Page Type from Standard Layout to Redirect.
Type or paste the tag filter link that you’d like the Page to redirect to. For example, /tagged/mytag, but replace “mytag” with the tag you want to use.
Check the box that says “Show a link to this page” and give the Page a title in the field next to the checkbox (e.g. Photos, Work).
Click “Create page.”
