Hi polimedia,

Thanks for getting in touch about this. It's quite a complex setup with some scope for setup problems.

In (1), you mention "the menu goes wild". Does that mean only that the wrong menu appears, or are there other layout or content issues in the menu? Sometimes if there are PHP warnings or errors reported this can mess up CSS styling which is extra visible in menus. In that case, turning off all PHP error/warning reporting can often help, at least to isolate if that's the problem.

I think I have actually seen this issue with the menu not getting translated, but I can't remember what the solution was... it's probably a plugin ordering issue of some sort. Does Falang have a system plugin for its database functions? If so, try ordering that before the main system Chameleon plugin and that may affect it.

You also mention that you can't get sessions to work, and it seems to forget the session after the 1st page. This is where Chameleon's Debug mode comes in handy. You can find that in the Options panel in the Chameleon rule chain page.

When you turn on Chameleon Debug mode, you get a list of the steps that Chameleon is taking, in the front end of the site. I suspect there may be an ordering issue in the Chameleon rules. You should be able to isolate that quickly with Debug mode.

I hope that helps,
Stephen
