On my site www.stata-bloggers.com some of the excerpts are showing full posts while others are showing excerpts. I have set the option to be only excerpts on the main page in Atahualpa but that does not seem to affect things. I have also turned on the plugin Thumbnail For Excerpts which displays thumbnails to the right of any excerpt. The plugin makes even the full posts display thumbnails leading me to me think that wordpress thinks they are excerpts but they are actually full posts.

I feel I have tried everything. I reinstalled wordpress 3.51. I have installed an alternative professional theme (magazine flow) which is supposed to be able to represent posts as excerpts but found the same posts presented the same problems.

Thank you for your time. Any help would be greatly appreciated.

disable ALL pluins at the same time and see if that changes anything
if not goto ato->export/import settings, export your settings and attach them to a reply

Just to make sure...

Do you have "Show the first X posts on HOME page as full posts?" set to 0?
