phpmyadmin,413请求实体太大

I am trying to import a small (75k) database SQL file into a new phpMyAdmin install, and am getting:

413 - Request Entity Too Large

php.ini settings:

upload_max_filesize = 150M      (originally 2M)
post_max_size = 150M            (originally 8M)

phpMyAdmin is not on SSL. It was installed as part of Zend Community Edition Stack running on Apache

Additionally, I am not seeing the error posted in /usr/local/zend/var/log/access.log

No mods have been installed that I am aware of.
