New to wordpress and new to the montezuma theme, so my apologies in advance if this is a very newbie question.
I just installed a new wordpress site, and selected the montezuma theme. I've only made one modification I found here at this forum to remove the -> arrows from the social link icons I included from jetpack.
I can't seem to get the autopost of a thumbnail to work correctly. My site seems to just point a broken image link on the homepage. I saw someone else having this problem here as well, and they fixed it by changing the permissions on the upload directory. I tried that and tried to resubmit the post and a new test post, but still didn't fix my issue. It appears that no thumbnail is being generated when I post and that's what's causing the link on the main page to fail.
Any ideas? My site is ultracompetent.com if you need to see what's going on. (Unfortunately I'm not yet ultracompetent with wordpress)
