I do love this plug-in and the new related posts feature is awesome. HOWEVER...it is in extremely bad form to have it automatically activated. I updated 30 client sites today all on the same server. Then all my sites went offline. WHY? It took awhile to determine but since I host them all in one place and they were all spidering all my sites in order to do the related posts my VPS ran out of RAM and shut down all 50 of my sites! THANK YOU VERY MUCH!
Now I have to go into every installation and turn it off manually (I'd added them all with InfiniteWP). May I respectfully urge you to reconsider this arrangement and change it to a manual turn on?!
Thanks for listening. I couldn't find anywhere on your support site to submit this. I hope an appropriate person sees it.
