Yep, ready to use. Or rather so it seems.
The boss wanted a blog software ... do you think WordPress was "install and go"? Nope, dude. I had to dig into the code to find out what the heck prevents it from working at all.
Later , the boss wanted a Wiki. We tried MediaWiki (PHP) ... we never ran out of problems. And it's far from warnings free. Apparently the authors never expected anyone to run it with warnings turned on. Which considering the fact that the warnings showed within the pages ... so we tried PMWiki (PHP). The same problems. The code is buggy. Compared to Foswiki (Perl) it's simply ... PHP. I had to dig into the code in all those cases. Neither of the installations was problem free (in the last case, because I needed to use IIS which is oficially not supported), but the Foswiki was still the easiest to get working.
Enoch was right!
Enjoy the last years of Rome.
