if i am not wrong those who are running Google
“Analytics 3 codes for WordPress” plugin , there is an issue with comments.
deactivating this plugin resolved the prob in my site.
(additionally i was unable to trash the comments)
for others
Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the Twenty Ten theme to rule out any theme-specific problems?
– resetting the plugins folder by FTP or PhpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.
