This is because you manually deleted the /etc/dokuwiki/htaccess config file. If it was not deleted by the purge, then it is a bug I do not understand in my postrm script. > 3.

DokuWiki plugins are usually run through DokuWiki's main scripts that define DOKU_INC correctly. However, some include parts that are directly called from the web: the acl plugin does so, with its ajax.php. In such a case, they have no way to get the DOKU_INC variable, so they try setting it to ../../../. This works on standard, manual installations. But with the Debian package, as there are parts that the user wants to change (plugins, templates) and parts that should only be managed by the package manager, I had to split the installation. That is why plugins are now under /var/lib, and will not find the inc/ directory at ../../../inc. This is problematic with plugins that have standalone scripts. To solve that I used a php_value command to define DOKU_INC, but that does not work with a php5-cgi setup, indeed. So I think I have two options: 1. replicate all the DokuWiki file hierarchy under /var/lib: this is delicate, as it would require yet another disruptive change, and a transition to manage, possibly causing new problems; 2. patch the built-in plugins to define DOKU_INC inside them, and leave the few third-party plugins that use standalone scripts not working, documenting in README.Debian how to patch them. Now let me think about the best solution… -- Tanguy Ortolo
