wordpress troubles? my banners arent showing up

hello; i have had wpress issues in the last few days.
i had not been able to access my posts; the message was that i didn't have access to them . i think it was a 4.1 code
i tried to check it this morning so icould share the code with you, but on my one site that this was happening on, all is back to normal.
on my other site w banners, it is the same issue continuing. on this site, the images of the banner have been replaced w the code itself.

my emailer service, getresponse, said it was a wordpress redo that caused the glitches; remove the getrsesponse plugin and redo the posts , inserting the banners again. But that takes a pile of time. Are u folks aware of any such issues? I'd sure like to hear from u about this.
thx
