Hi there,
I have a very similar problem, maybe
I already had a working version of limesurvey200plus-build121019.tar.gz running on my host.
Because I need SSL and have an old server with an Ubuntu Hardy in use (ok, that's another story) I recompiled openssl and Apache version 2.2.23 today. It looked good as all websites were running w/o problems.
Limesurvey does make problems now that I can't define any further. I can't open any user or surveys, they just won't open. Already tried reinstalling the whole setup with database, etc.
Activating the debug-mode it throws an exception (see attachment for full view):
The URL pattern "<_sid:\d+>/lang-<_lang:\w+>/tk-<_token:\w+>" for route "survey/index/sid/<_sid>/lang/<_lang>/token/<_token>" is not a valid regular expression.
Looks like any problem with mod_rewrite, but it's there, ist recompiled and it is working in other instances, so does anyone got further hints where to follow up debugging this?
Thanks in advance!
Carsten
