I’ve had to deactivate this plugin because the issue is so pervasive. Once I deactivated it, the permalink problems seem to be resolved.
I am using a Kriesi theme with Portfolio pages. All of the portfolio pages that I’ve made changes to within the last few days have had the permalinks changed to the names of random blog post titles. In addition, preview text is stripped from the page each time I open the page for editing, which affects top level pages. Now I have to check every page of the website and change the permalink manually. This bug is VERY bad! Google has already indexed these new URLS, which is terrible. Please fix this soon or a 1 star rating will be coming your way and I will be switching to a different plugin.
