Thanks jdembowski for offering help.
Okay, here's a detailed example of what's occurring, but it appears it hasn't occurred for all my posts, just some.
The permalink structure I had established for my site is like this example:
http://www.linkandblog.com/2007/06/23/improve-bounce-rate/
But, Google has some of my posts indexed with weird urls, so for the post I have shown above, it's currently indexed like this:
http://www.linkandblog.com/?s=panicking
The word, 'panicking' happens to be in that post, but for the life of me I cannot figure out why this is happening. To my knowledge, this didn't occur until after I upgraded from 2.7.1.
And, 'panicking' is exactly what I've been doing over this because I tried to get this resolved prior to Googles pr update the first of April, but failed to by then, so my pr is stagnant now. So, now I'm hoping to get it resolved prior to the next one, because I lost pr some time ago, and I'm hoping to fix it to gain it back soon. Thanks!
