I installed the SPARTACUS plugin, so I see two new options when configuring plugins : "Click here to fetch a new sidebar plugin from the Serendipity Online Repository" and "Click here to fetch a new event plugin from the Serendipity Online Repository"
The sidebar thing shows what it's supposed to show : a list of extra plugins...
The event thing shows only this :
How come and what to do about it?"Trying to open URL package_event.xml...
Fetched 80830 bytes from already existing file on your server. Saving file as templates_c/package_event.xml..."
Thanks, B.
