UPDATE core_members SET signature=REPLACE(signature, '<___base_url___>/uploads/monthly_','<fileStore.core_Attachment>/monthly_');
UPDATE core_message_posts SET msg_post=REPLACE(msg_post, '<___base_url___>/uploads/monthly_','<fileStore.core_Attachment>/monthly_');
UPDATE forums_archive_posts SET archive_content=REPLACE(archive_content, '<___base_url___>/uploads/monthly_','<fileStore.core_Attachment>/monthly_');
UPDATE forums_posts SET post=REPLACE(post, '<___base_url___>/uploads/monthly_','<fileStore.core_Attachment>/monthly_');
UPDATE core_member_status_replies SET reply_content=REPLACE(reply_content, '<___base_url___>/uploads/monthly_','<fileStore.core_Attachment>/monthly_');
