Apparently, the Custom Search Box is not working on Blogger Blogs at the moment. Here is a quick way to add a basic search box to blogger.
Add a Simple Search Box to Blogger
I thought, at first, this was an issue only I was experiencing as I have recently updated my blog with a custom domain.
I checked the forums for a workaround and discovered it is apparently a problem with the Custom Search Box – not related to me adding a custom domain to my blog.
This will give you a simple and functioning search box – you can use it forever, or replace it with the Custom Search Box once it is fixed.
So if you are on Blogger, you may want to try to search your own blog to see if your Search Box is working – and if it is not working – you can use the fix above too 🙂
