* I use dyndns, so I need multiple hostnames to be able to access the blog via localhost as well.
* Since I have a local cvs snapshot, I symlink it to the plugins directory.
So these are the plugins I was talking about:
1. serendipity_plugin_freetag: Uses an absolute hostname for the tag link. In my case, this means the tag links always point to the dyndns hostname. I have set a relative path in the plugin config, which works just fine. Unless there's something I don't see, I think this should be the default.
2. serendipity_event_freetag: see 1., it's exactly the same behaviour.
3. serendipity_event_twitter: Doesn't like the fact that the plugin dir is a symlink in my case. It seems to try and resolve the symlink, which doesn't work and breaks the path to at least the tweet-this-button images. Setting the correct plugin path solves it.
I admit that the symlink stuff is something probably only developers use, but I thought I'd mention it anyway.
