"missing lang.js" since Feng update

[crostif]

Hi, i used opengoo since a long time without any problem with it.
Recently, i decided to update to Feng office 1.62, and 1.7. With these two versions i have the same problem each day : the error message "missing lang.js" appears instead of each menu, and no fonctionnality is enabled.
When it appears, i have to reinstall feng office and to affect the ancient bdd. Then, it works again for one day. If i only transfer by ftp files that i have saved, it doesn't work.
The problem is during since a week...
I haven't found any response in precedents subjects which talk about this.

Any ideas ?

thanks.

When you replace files, are you sure Unix permissions are set correctly?
It looks like you are working with a cache version for a couple of days and when it tries to get the new version it fails.

Thanks for your answer.

In fact, i do not sure of permissions, but i tried a fiew combinations for test : all permissions in 777, only the lang folder in 777, only th lang.js in 777.

How can i empty the cache ?

Try setting the owner of the complete Feng Office folder recursively to apache, and permissions to 755.

Feng Office Cache is in cache folder, but it has never caused an issue. I was talking about emptying your browser cache.
