Hi again Carolyn,
First: as to why your messages were bouncing - did you ever formally make an account with this email address in the User Forum? We adjusted the settings so this is not required to post, but in some cases (often when users respond to threads too quickly for the filters, is my best guess) repeated posts will be flagged as spam. I've tried to write up a short FAQ about this here:
After consulting with one of our developers and looking at some of the links
in our previous thread again, one of our developers pointed out the following:
Please visit the following URLs (one from your site, one from our demo site) and right-click and view the page source from each:
You will notice that even on a non-export page, there is a blank line of whitespace in source code, which is not present in the default version. I strongly suspect there is something in your custom theme causing this - likely in the header or one of the other layout templates.
You could try changing back to the default Dominion theme via Admin > Themes, and see if this allows your EAD exports to proceed - this should help us confirm that it's the theme causing the issue. It could also be something on the server side - a specific webserver config or something - so start with this. Hopefully if we can narrow things down, you can go from there.
Let us know how it goes!
