I have a hierarchical menu system on Joomla 1.5 and have been repeatedly switching between two language translations (German and Italian).
I have noticed that the links in the menu system get confused and I end up seeing URLs with
/de/it/
in them. Obviously the system has got confused along the way.
I tried to fix it by turning off caching just for the menu systems in Joomla. That failed.
I then turned off caching for all of Joomla and that seems to have made the problem go away.
My web pages are relatively small and so I guess for the time being I don't need caching. The website responds at a decent speed without it anyway.
But I was wondering if anybody else here has tested Joomla 1.5 and GTranslate aggressively by switching between language with a hierarchical menu system and found turning off caching fixes problems.
