First of all - super plugin!
I think I've uncovered a pretty critical bug.
I have some guests who have names with apostrophes
e.g. Bill O'Neill
Upon attempting to login on the frontend, the user sees:
We were unable to find anyone with a name of Bill o\'neill
So it would appear that character escaping is preventing Bill from logging in.
I checked wp_attendees and I can see the record is stored as "Bill O'Neill"
Any ideas as to what code needs to be changed for this to work correctly? I have about 100 guests all due to get invites in the next 36 hours and about 30 of them have O'Neill surnames!!
