[rt-users] Can't use string ("") as a HASH ref while "strict refs" in use at /opt/rt3/share/html/Elements/MyRT line 50, <DATA> line 1662

[Richard Ellis]

Hi Jesse,

I have just removed all content under local/html and also dropped and 
reinitialised the database and still see the same error. The only thing 
I can think of is it must be a compatibility issue with one of the deps.

I'm checking an autobundle of our perl version 5.8.4 against the 
testdeps requirements, one line at a time to try and find the culprit.

Thanks

Rik
