The xmlrpc libraries that came bundled with b2evo were slightly modified from the normal ones, in such a way that they defined a function that didn't exist. So, when trying to add something to my spam blocking, and it attempts to report it to b2evolution as well, it fails since this function doesn't exist. Error: Reporting abuse to b2evolution.net... Fatal error: Call to undefined function: xmlrpc_decode_recurse() in /home/halcyon/www/blog/b2evocore/_functions.php on line 610 The same occurs when trying to update the blacklist from the central server.
This seems to be the patch for the issue, instead of copying the new libraries over what is currently there: http://prdownloads.sourceforge.net/evocms/xmlrpc_fix_112.zip?download
Fixed in the tree.
