I'm using "throw new Wire404Exception();" in my template, it worked fine. After Migrating to an other server and Upgrading to PW 3.0.62 I got an Error "Class 'Wire404Exception' not found" . I spent the day yesterday unsuccessfully to understand the reason. Is there any reason, why PW can't find this class? The Exceptions.php in wire/core exists.
I beg your pardon, if this topic should be discussed here yet - the search items 'Wire404Exception' and 'not found' leed to many other results not related to the class itself.
