What you should do : Fork the plugin from the best version you can find, read the documented changes since the API for which the plugin was built (to be found in PMMP's release page on github), update the plugin code to reflect those changes, update any deprecated function calls, use new functionality provided by the latest API for better efficiency and readability, test, fix, repeat until everything works, submit a pull request. What everyone does : Download the plugin as a zip file from a discord chat, change the API version, run, try to fix errors in console once by one without bothering to refer to the documented API changes, repeat until you need to post here for help.
