Some strange behavior with this plug-in. I created site and used this plug-in. At some point of time noticed that plug-in is broken. Was not able to fix it, thus created clean WordPress deployment. Plug-in worked fine with this clean deployment. Again, something broke the plug-in and it started to show this ugly post confirmed. I fixed it by adding a redirect as proposed earlier in this discussion. This is just as information that something is wrong with plug-in. My educated guess is that it is somethign related to permalinks. I changed setting at some point, but did not remember to try this plug-in immediately after this, thus cannot confirm my statement.
