After upgrading to Wordpress 3.1.4, I noticed that some of my post titles are being duplicated?

I cant seem to find what is causing this problem.
I am using All-in-one SEO plugin and Meta SEO pack as well.

Have tried deleting the post title but it stays there?
What am I missing?

where to correct this?

first thing to try is reset your permalinks - change it to the default then back to what you have now.

Do you have all BUGFIX's for your version applied? (they can be found in the 'New Version & Updates' forum and sub forum)
--if not, apply them before we go any further and re-test

Thanks Juggledad

Resetting the permalinks did not work.

I looked at the bugfix from the other thread you mentioned, downloaded it ... now what do I do with it?
(sorry my knowledge of web page building is on a need to know basis ... I havent needed to know this yet )

did you follow the directions? Also apply ALL the fix's for 367

Thank you got that fixed now!

"Also apply ALL the fix's for 367" ... one was enough for today thank you!
