Architecture / Installation

I was referring if there was a tiki error logfile.

Isn't also possible to give some error output (for future version)
Like:
Unable to load Tiki, error in - language.php
Unable to load Tiki, error in dbase - wiki_pages

So you have some clue where to look.

I see no other solution then to install a fresh Tiki and try to migrate the existing dbase, hopefully not copying the error.

or a debug parammeter.
which creates a txt file with an output of every succesfull loaded part.

Like index.php -debug

language.php loaded ok!
....... loaded ok!
