Just did CVS update and found that the notifications screen loads quickly and is completely blank. I have nwiki 2.0 installed and the AJAX marking block but no other extras. Update last night was fine. php error log shows: [12-Nov-2007 11:53:05] PHP Fatal error: Cannot redeclare class block_wiki_contributions in C:\MoodleWindowsInstaller-latest-16\moodle\moodle\lib\blocklib.php on line 1192 [12-Nov-2007 11:55:12] PHP Fatal error: Cannot redeclare class block_wiki_contributions in C:\MoodleWindowsInstaller-latest-16\moodle\moodle\lib\blocklib.php on line 1192 [12-Nov-2007 11:56:17] PHP Fatal error: Cannot redeclare class block_wiki_contributions in C:\MoodleWindowsInstaller-latest-16\moodle\moodle\lib\blocklib.php on line 1192 [12-Nov-2007 11:56:25] PHP Fatal error: Cannot redeclare class block_wiki_contributions in C:\MoodleWindowsInstaller-latest-16\moodle\moodle\lib\blocklib.php on line 1192 [12-Nov-2007 11:57:00] PHP Fatal error: Cannot redeclare class block_wiki_contributions in C:\MoodleWindowsInstaller-latest-16\moodle\moodle\lib\blocklib.php on line 1192 [12-Nov-2007 11:59:34] PHP Fatal error: Cannot redeclare class block_wiki_contributions in C:\MoodleWindowsInstaller-latest-16\moodle\moodle\lib\blocklib.php on line 1192 [12-Nov-2007 11:59:36] PHP Fatal error: Cannot redeclare class block_wiki_contributions in C:\MoodleWindowsInstaller-latest-16\moodle\moodle\lib\blocklib.php on line 1192
