Github pages displaying ghost content


I have a page on Github pages for a few years now. Recently I decided to modify the whole page and remove the old content. The problem is that, whereas most pages are working correctly, the /blog link is still pointing to the old version.



I have tried:

1 - clearing the cache of my browser

2 - opening on other browsers

3 - removing the master branch and recreating it

4 - removing the whole repository and recreating it

 The old pages that appear there are not even in the repository at all! Does anyone have an idea on what could be the problem and how to solve it? 

have you got base_url set in your config to /blog maybe, so it is still pulling old content from the previous location?
