The “Cannot redeclare function” error seems to be related to php 5. Many plugins doesn’t work on my side when using php 5, since they “seem” to be written in the php 4 way. When I use insteed php 4.4, everything works well.
Maybe the error given to you by php 4.3.1 is induced by same problem ?

I don’t get this working, but anyway, there is plenty of php 4 user out there 🙂
