Sorry, was my fault, I've disabled javascript, that was the issue with the preferences.
Local and global search does work, but there are very few results (around 20 with only one source for the search term 'debian'; mostly just .torrents)
The output of aMule if I start a search is the following:
PHP Warning: Sorting array of size 0
The kad-page in the webinterface is blank and I cannot search using kad, don't have enough time atm to build remote gui to check this out.
I use 20051214-tarball.
