I was able to get the field back by deactivating, then reactivating the plugin. So I guess it’s a minor issue, but the solution is not very elegant. Seems like this can be easily addressed by the developer.
I just installed 3.7.1 and behold the answer is there waiting for me when I activated the theme.
No PHP inserts since 3.6.5. The loop code is now hard coded into index.php (in case anyone else was wondering the same as me)
…bummed out that nobody could help. I was able to trouble shoot the problem myself and figured I would post here in case anyone else runs into this…
The problem was not with my $_POST variables, it was with PHP Exec plugin. I was unaware of the “globals issue” with the plugin and this was causing some unexpected behavior. Linky: http://bluesome.net/post/2005/08/18/50/#globals
I did stumble across another tip and that was to leave the form action blank (“”) in order for it to post to itself.
