I have successfully migrated my WordPress site, but nothing is displayed
Judging by the error, it seems that some files are missing from the plugin.
I don’t remember exactly whether uninstalling a plugin will also delete all associated data. I suspect that it does, in which case you should not just reinstall it.
However, you can simply reupload the files of the website without data loss. You can download a fresh copy of the plugin files, extract them to your own computer, and upload the contents to the `ahmp.org.pe/htdocs/wp-contents/plugins/revslider/` directory, overwriting any existing files. That should restore the missing files.

That said, as far as I can tell, “revslider” is called Slider Revolution, which is a plugin that costs $109 to use. If you’re not paying that, it either means that you’re probably using a pirated copy, which is illegal, and therefore not allowed on our hosting.
The same is true for the Ave theme by the way, that’s also a $39 theme. If you haven’t paid that, and just “got it from somewhere” for free, that’s an illegal copy, that’s probably outdated and likely has malware in it.
Many good free themes and plugins exist for WordPress. Some paid themes and plugins are better, but then always actually pay for the license and don’t just find an “alternative download” where you don’t have to pay. That’s very illegal, very dangerous, and very prohibited on our hosting.
