Errors using WAMP for local hosting site and Dreamweaver to edit theme

I would like to make offline edits the theme of my live wordpress site using Dreamweaver.

Setup:

Running Windows 10 64-bit and Wamp 64-bit and have exported my database from the live site to the localhost through phpadmin. I'm making sure that the wp-config file has the correct database info and that I'm using incognito mode in Chrome to avoid any cache related issues.

Errors when plugins are enabled through database:

Fatal error: Class 'SiteOrigin_Panels_Revisions' not found in C:\wamp64\www\catalog\wp-content\plugins\siteorigin-panels\siteorigin-panels.php

Errors when plugins are disabled through database:

localhost/catalog/wp-admin redirects me to the live site login when expecting it to take me to localhost path login localhost/catalog/wp-admin.php/ redirects me to my main page

Dreamweaver errors: "Dynamically-related files could not be resolved because the site definition is not correct for this server." I am getting this error even with permalinks set to plain and when I have my testing server setup according my wamp folder path as localhost/catalog and server model selected as PHP MySQL.

I just want to be able to host locally with plugins active and be able to edit the html of the index of my main page localhost/catalog- but it is a php file, so I went to Live Code View in Dreamweaver, copied and pasted that html code that shows up in Live Code View, and pasted it in an html file, but then this html makes the site look all messed up.

Any help for any of these problems would greatly be appreciated. Thanks.
