The other day I mistakingly sent my wordpress ID and username through this system. I got an email from Kika letting me know how fortunate I was nobody got it. True enough. Not sure how I was supposed to do that.
Since I got so concerned, I changed my password to ensure nobody tampered with my site.
My problem with my blog not showing up through the page I have set up on the main menu still exists. When you go to the page I have set up for the blog (which I can see when I to to it through the side panel) it says “File can not be found.” I know it’s not seeing the link, and I have tried to set it, but no luck.
For the life of me I can’t seem to connect them…….what am I missing? I’d like this to work.
Thanks for your help,
Ken
