In your config/custom.config.php file make sure you have the following settings:

debug.level                         = All
debug.error_reporting               = E_ALL & !E_DEPRECATED

zend.logger_level                   = DEBUG

The debug settings are probably already set this way. But if not, will cause runtime errors to be reported in the tmp/log/php.log file.

The zend.logger_level setting will have a lot of debug information to written to the tmp/log/si.log file.

If your problem still exists, zip these files together and attach to a message added to this thread.
