求助！安装zencart后台空白

ingiz

本地调试没问题，在空间里面安装后修改了数据库，文件地址后，前台也没问题，但是进入后台就空白，查错误时报下面的提示：
Warning: session_start() [function.session-start]: Cannot send session cookie – headers already sent by (output started at /home1/megacoll/public_html/shopping/admin/includes/classes/logger.php:106) in /home1/megacoll/public_html/shopping/includes/functions/sessions.php on line 108 Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent (output started at /home1/megacoll/public_html/shopping/admin/includes/classes/logger.php:106) in /home1/megacoll/public_html/shopping/includes/functions/sessions.php on line 108 Warning: Cannot modify header information – headers already sent by (output started at /home1/megacoll/public_html/shopping/admin/includes/classes/logger.php:106) in /home1/megacoll/public_html/shopping/admin/includes/init_includes/init_templates.php on line 69 Warning: Cannot modify header information – headers already sent by (output started at /home1/megacoll/public_html/shopping/admin/includes/classes/logger.php:106) in /home1/megacoll/public_html/shopping/admin/includes/functions/general.php on line 37
