I've duplicated a site into a new development environment, and everything works as it should other than the Entries section. It throws the AJAX-based "unknown error", originating from a 500 error on getElements action. Attempting to bring up that request directly results in a "Bad Request - The request could not be understood by the server due to malformed syntax." screen. The isolated log from the incident included here:

I've tried recopying the working site files and database, but this exact same issue shows up each time. Could it be an environmental issue? Despite tracking it this far, I'm at a loss.

A little more pouring over the logs came up with the specific "only_full_group_by" MySQL error. This put me back on the trail, which lead me here: Getting this SQL Error: GROUP BY incompatible with sql_mode=only_full_group_by

It appears the most straightforward approach is to add this line to your environment within /craft/config/db.php:

'initSQLs' => array("SET SESSION sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';")

Thanks again, Brad Bell!
