RSS Feed errors abound

I’ve been trying to figure this out for days. I initially thought it was down to some plugins, but I’ve since disabled those and the problem still exists. When I try to view the feed for https://www.thewanderingbrit.com, (www.thewanderingbrit.com/feed/), I’m getting feed validation errors. Different validators and programs put it different ways, but here’s a few descriptions of what they say is causing the parsing issue:

This page contains the following errors:

error on line 32 at column 66: EntityRef: expecting ‘;’
Below is a rendering of the page up to the first error.

——————————————–

This feed does not validate.

line 32, column 73: XML parsing error: <unknown>:32:73: not well-formed (invalid token) [help]

<guid isPermaLink=”false”>https://www.thewanderingbrit.com/?p=752&iphone=tr …

I’ve been trying to sort this out and research this for a good few days now and noone seems to have any good answers for me. Can someone PLEASE lend a hand?
