They look like this:

&quot;You don’t improve education by demoralizing the people who have to do the work every day.”<br />-Diane Ravitch

How can I get it fixed?

first run this SQL query for testing

SELECT * FROM `mybb_users` WHERE `signature` LIKE '%"%'

if you get a list of signatures with &quot; then try below

UPDATE `mybb_users` SET `signature` = REPLACE(`signature`, '"', '"') WHERE `signature` LIKE '%"%' 

same for the <br / > thing?

^ yes, that should work..
