Given the question: What would be the ★-rating of this review (★ being the lowest and ★★★★★ being the highest)? "Irritating for me. I can login successfully to my self hosted site but when I try to upload an image or media  this app shows an error ""Media upload error: Precondition Failed"". Plus when I press the publish button  the posts are saved locally on draft. It says ""Post Upload Failed"" I have tried increasing max. file upload size on hosting and fixing xmlrpc file but nothing worked because that is what I found on Google about this issue. I even posted this issue on WP forums but I haven't received any reply for months yet. So in simple words  this app is just trouble for new users."
The answer is:
★★★★★
