Oddily enough I am having a similar problems, I have had a feed reading threads into my site for some time now. Recently I discovered that from around November last year it was no longer adding new threads.
After a little investigation I haven't found the solution, however I have found the following:
- If I reset the feed then it works on the next scheduled run or if I run it manually from the RSS manager page.
- Deleting and re-adding the feed doesn't make any difference.
- The feed is configured to check every 2 hours, however the last date checked does not move on from the date/time of the first check after a reset.
So right now I periodically reset and run the job, and when I find some time I will investigate further.
I have not yet raised a ticket at vb.com as I know the first response will be disable all mods, which is something I don't want to do as I have no mods that use rss hooks and as mentioned I haven't yet had a chance to fully investigate the issue.
