When writing drafts for my blog posts, I prefer to use offline blog authoring editors. First, I used Windows Live Writer, part of Windows Essential, but after it reached end of support in the 2017, I switched to forked open sourced version Open Live Writer. I also installed EasyPHP on my local machine, to publish the drafts to my local WordPress site for further processing. The problem was that the "Open Live Writer" was not letting me add a blog account. It was giving me an error message about Invalid Server Response. In this article, I will show you what I tried and what fixed the issue.
