I recently have been tasked with revamping my job's website, it was created with WP. But it seems that most plug-ins are old, slow, no longer working the way they should be & are unable to be updated, it seems we have to pay for the latest versions of each thing "WPBakery, Theme, Slider Revolution, etc" which I really don't want to do. Is there any recommendations on how to work this? It seems super complicated to me but I am try to to find a way to get this done without messing up the website or cause any errors. Does anyone have any experience and/or recommendations on where to begin?

I have a WPengine login, if that means anything. I am unsure if that helps.

I have experience with square space, but WP seems like a completely different ball game. Please help!
