The SEO plugin by Mark Johnson causes BIG problems in Chrome. I couldn't work out what the problem was but i couldn't upload images, access the content in my widgets. It basically froze all the roll-over functions in the admin.
I installed it because it has the highest ratings, but afterwards realised it's because there's only 2 ratings.
This was filtered to the top of the SEO search because of it's rating.
And it basically wasted me a LOT of time. Hopefully this will prevent someone else having the same problem
There should be better filtering on ratings within wordpress as well. A product with only 2 ratings shouldn't appear first.
