I have been using Post Indexer together with Recent Global Posts Widget for a while and it has been working fine. However, today I went to my site settings page to disable posts from being indexed for a specific site and then it stopped indexing topics (bbPress) for that site too. I still have topics as a choice among the checkboxes, but I check it, save and it is uncheched again. I have been able to display my recent forum topics for many months now, but now I cannot anymore. I tried deleting the plugin and installing it again, but topics can no longer be indexed. What is the problem?
