Claiming that you didn't do anything else is pointless.
I saw the error message from your site that said it was looking for a file you renamed.
The plugin doesn't rename any files. You even said in an earlier post that you renamed files from wp- to jp-. Never in the history of WordPress has anyone ever said to do that.
You misunderstood that the purpose was to rename the database tables from wp_ to something other than wp_.
The plugin's code can not change any file names, and it can not overwrite any content in the database. It is not possible.
You're correct that for a very few users, the automatic table renaming functionality doesn't work (I told you this a few posts ago). However, it just simply doesn't do anything, and gives you a message as such. That has nothing to do with your issue.
I'll say again, you should have read the documentation and/or asked before doing something that you obviously had no clue about, leading you to change WordPress core filenames.
Considering that the website in my profile is the same website for the plugin and also that WP Security Scan is under my profile, yes, obviously I'm the author of the plugin.
