In general getting WordPress installed on webspace at HostEurope goes very smoothly – however using the automatic update function or sending notification mails to users caused some problems to me initially.
In order to get both thing to work properly, I put together a very tiny plugin called th23 HostEurope Fix – for use, just download it, extract the zip-file and upload the folder “th23-hosteurope-fix” into the plugin directory of your WordPress installation. Activate like any other plugin via the “Plugins” section in the WordPress admin area, and you are done.
