"In late September an intermittent problem started and was recently resolved. Some of the slave servers were getting out of sync with the master database. It is quite possible that during this time wikis were not being indexed properly or not at all. As stated the problem was recently corrected with the syncing of master/slave servers. It may take a little longer for all of the Wetpaint wikis (1 million plus) to be re-indexed to a current status.
If you still have this problem in a weeks time, I invite you to message jeremy_wetpaint,who is the product support for Wetpaint to have your wiki manually re-indexed at Wetpaint."
