Warning Error after install

I downloaded the new version of Wp, and finally got the database name and such correct. The only issue I’m having is that at the start of each of my posts, I’m getting a string of errors. Once the string of errors is done, the post shows up normally… that is until the next post begins and a new stream of the same errors appears.

Here’s a copy and paste of the error string. Please help.
