@vladmir,
The new update actually broke the plugin.. Now single post page shows alt and title attribute for images with unnecessary \ which is causing wrong alt & title attribute..
for example: <img src=”image-name.png” alt=\”image name”\ title=\”image post name\” />
The backslash is appearing in html source code and therefore browser is not reading the attribute properly.
I fixed it for myself by removing the backslash in the source code of the plugin..
But you should urgently fix it otherwise thousands of your users will face this problem
