Obviously, normally a deactivated plugin doesn’t do anything, but there are a few exceptions, e.g. caching or security plugins that modify .htaccess for instance.
What is the plugin?
Can you not ask the plugin support directly
The plugin is https://ww.wp.xz.cn/plugins/disable-right-click-for-wp/
The plugin developer does’nt support it from what I could see.
The plugin is simple, it has only two files, and less than 100 lines of code. I could understand that it does an add_function() with the javascript code. However, I have looked everywhere possible for this code to remove it, but so far nothing.
OK, so I right clicked your site ( by turning javascript off ) and inspected and I looked at the code of that plugin, and I can tell you that that plugin’s code is not loaded.
Therefore, something else is stopping the right click.
It could be another plugin. It could be a snippet in your theme.
Probably the best thing to do is to install the Trouble Shooting & Health Check plugin. This plugin allows you to disable all plugins and themes without impacting any other user. Then you can check and use a process of elimination re enabling one thing at a time.
