Hi,
What permissions must the debug.log be set to?
I've just recently upgraded from 1.4.5.1 to 1.4.5.9 and the update script din't complain about permisions
This is what my apache error log file is reporting
PHP Warning: fopen(/var/www/albums/zp-data/debug.log): failed to open stream: Permission denied in /var/www/albums/zp-core/functions-basic.php on line 1236
PHP Warning: file_get_contents(/var/www/albums/zp-data/debug.log): failed to open stream: Permission denied in /var/www/albums/zp-core/admin-logs.php on line 87
