Help! Deleted post and now excerpt is still showing

Hey!

Ok, so I am in a rather bad situation here. I deleted a post out of my blog https://www.divinemercynow.org/blog and I thought that the excerpt would be deleted as well. I was sorely mistaken and now the excerpt is making it’s normal rounds on my Non-Profit scroll bar on the bottom. The name of th story that I deleted was (Heroism still exists). You can view this on my site at https://www.divinemercynow.org

I have gone through everything I can to find these excerpts and cannot find them in order to delete them off so they will not be circulating on my site. I did go into the wordpress install folder and deleted the picture off of the scroll.. however now it is showing a blank for the pic and the excerpt is still making it’s rounds.

Please help me, I have searched high and low on google for an answer and in these forums to no avail.

Thanks,

Michael
