Hello all I have just had a conversation with my web administrator, and he shut down the comment facility, while he investigated the AKISMET anti spam plug in. The comment facility stayed closed until I had an anti spam plugin in place. This will block computer generated spam, and spam originating from the same IP address.If anyone out there is having similar problems look on the WordPress help forum.
UPDATE Akismet anti spam plug in is now in place. All the previous comments have been put in the trash folder for re- evaluation. I will gradually reinstate those I am convinced are genuine but it may take time! Apologies for any inconvenience to genuine contributors ..Judi
