The response is not a valid JSON response. After a site migration I got this error. Don’t panic, this was an easy fix, go to Settings > Permalinks and choose ‘Post name’ then press the save button. Easy right? Happy WordPressing! ← Could not create directory. Installation failed. Leave a Reply Cancel replyYour email address will not be published.
