JoomFish PHP problems with Joomla 1.5

I just installed JoomFish, the translation content manager, for Joomla 1.5.9 on my 1and1 hosting service, and right away ran into PHP problems.

How did I solve it? It was pretty easy. I had to turn the PHP files into PHP5 in order for JoomFish to work.

Here’s how to do it: How to run PHP5 on 1and1.

And hey presto: it worked!
