There doesn't seem to be any threads concerning reccomended plugins for the Original. Only Woo. Congrats! This thread is a first!
Many plugins (free and paid) do not work with the Original, but here are some useful ones that do.
From Alidropship .. https://alidropship.com/addons/
Alidropship's Abandoned Cart
There is also Customers Gallery and Google Analytics for free there ... but they're not that important.
From WP-Admin>Plugins>Add New (Search Box)
Mailpoet Newsletters
Wordfence Security
WP Super Cache
Open Graph for Facebook, Google+ and Twitter Card Tags (Ignore the Google+, it's been scrapped)
WP Chatbot
SMUSH (Image size reducer)
There's others you could use, but they are not "must have", like
WP Quiz (post links to quizzes on your site to bring traffic)
Enhanced Media Library (Makes categories for images to make it easier to manage them)
Then are are other ones that use shortcodes, but you'd have to make a child theme and edit theme files to use them.
Anyone else with more suggestions?
