Joomsef shouldn't interfere with the plugin unless its failing to set the language properly.
The language has to be set also in the default one, that's why! well, it isn't necessary with joomsef turned off proobably..
Anyway it's solved!!

Hi!
I'm new here!
I've a problem with joom sef and joomfish Content Table Localisation Plugin.

My site default language is italian and some contents are hided in the english version, the joomfish plugin's behaviour. Contents are hided with joomsef turned off, but not with it active..

Any suggestion?

using joomla 1.5.14, joomsef 5.3.5 and joomfish 2.0.4
