Torven posted in the webtrees forum he got it working:
To get it working I commented out lines 741, 742, 743 in the file functions_dot.php
The lines now look like this: // $func="datelocalisation{$lang_short_cut[$LANGUAGE]}"; // if (!function_exists($func)) // $func="DefaultDateLocalisation";

My understanding of PHP is fairly poor so don't ask me what I've changed.
You can test it here if you like: zeffertt.uk/webtrees/
Cheers, Torven

Was unused code from previous maintainers... So commenting this out was actually a very good solution :)

I removed it to fix the problem permanently
