Some WordPress plugins (one is MapPress which uses Google Maps) use ampersands in their links but do not convert them into the correct HTML character entity:
&
This invalidates the markup and is very frustrating!
Is there any way to convert the & to &?
I’ve searched for a long time and found no solution, but have read a lot of interesting articles on the topic!
I’d write an email to him and ask him to use
htmlentitiesin his plugin. Even better, make the changes yourself, then email him a patch.
