@Len - Ahh, I see now. I once tried to use Broken Link Checker on WPTavern which is also on that list and it too caused major problems lol. Never was able to see all the broken links on the site. Interesting to see Google XML sitemaps on that list. That's another plugin I've used for along time but never thought it would give me problems. At least I don't think it's ever been a problem for me.
