There is one biggest mistake when you are upgrading your wordpress with this plugin. It’s forgetting to upload the files in the wp-admin folder. Usually, wordpress instruction for upgrading the software is deleting the wp-admin and wp-content directory and its contents. But after upgrading, I don’t about you but in my experience I forgot to upload it again so I thought there were something wrong with the plugin compatibility. I disabled it for a long time thinking that it was a plugin problem.

Now I know that human error is also a software problem. So the next time you upgrade your Wordpress, don’t forget to upload those files! ;)

Update: I have removed the plugin because I don’t need it anymore.
