So I experimented briefly this past week with a different plugin that was running the Disqus Script... That plugin disabled the Disqus Auto Sync feature of Disqus so that the comments did not sync with WordPress Comments.
Now I have uninstalled that other plugin and have reactivated the Disqus for WordPress Plugin, and everything is working fine as usual with the auto sync feature. However, all the comments that were entered on Disqus during that week which I experimented with the other plugin will not sync to WordPress. They still show up in the Disqus comment section, but whenever I try to sync Disqus with WordPress native comments, they do not get pulled over into the database.
Any idea how to fix this?
