As soon as your question arrives I will add it here.

Some weird error message

Do your server run php5? We need the "DOM" section of your phpinfo() show "enabled"-values.

There's an error message like "ERROR: domdocument::domdocument() expects 2 parameter to be long"

Disable the domxml extension of your php installation. domxml is a legacy extension introduced for php4 which lacks cool dom-functions. But in php5 they are built in and - guess what - incompatible with the old extension. So we rely on the new bright and shiny built-in functions.

Can I use this plugin without a widget?

Unfortunately this is not possible. As all options are set on a per-widget basis, there is no way to display a list without a widget.

Can you translate the plugin to language [insert-your-language]

No... but: You can! Just have a look at the translation files and/or contact me for further instructions.
