\r\n

If you see white empty screen trying to access your PrestaShop store this means that there is some server error occurred. <\/p>\r\n

Enabling errors display<\/h3>\r\n

1. First of all, you can enable built in Debug Mode<\/strong> of PrestaShop engine, open config\\defines.inc.php<\/strong> file and locate the following line:<\/p>\r\n

define('_PS_MODE_DEV_', false);<\/pre>\r\n
replace it with <\/p>\r\n
define('_PS_MODE_DEV_', true);<\/pre>\r\n
Enabling errors logging<\/h3>\r\n
2. To log the errors without displaying them, you need to open index.php<\/strong> file from the root of your PrestaShop installation and at the top add the following code:<\/p>\r\n
\r\n<?php error_reporting(0); \r\n$old_error_handler = set_error_handler("userErrorHandler");\r\n\r\nfunction userErrorHandler ($errno, $errmsg, $filename, $linenum,  $vars) \r\n{\r\n$time=date("d M Y H:i:s"); \r\n\/\/ Get the error type from the error number \r\n$errortype = array (1    => "Error",\r\n2    => "Warning",\r\n4    => "Parsing Error",\r\n8    => "Notice",\r\n16   => "Core Error",\r\n32   => "Core Warning",\r\n64   => "Compile Error",\r\n128  => "Compile Warning",\r\n256  => "User Error",\r\n512  => "User Warning",\r\n1024 => "User Notice");\r\n$errlevel=$errortype[$errno];\r\n\r\n\/\/Write error to log file (CSV format) \r\n$errfile=fopen("errors.csv","a"); \r\nfputs($errfile,"\\"$time\\",\\"$filename: \r\n$linenum\\",\\"($errlevel) $errmsg\\"\\r\\n"); \r\nfclose($errfile);\r\n\r\nif($errno!=2 && $errno!=8) {\r\n\/\/Terminate script if fatal error\r\ndie("A fatal error has occurred. Script execution has been aborted");\r\n} \r\n}\r\n?><\/pre>\r\n
Save the file and try to access your PrestaShop store or admin panel. <\/p>\r\n
After this you’ll be able to see   errors.csv <\/strong> file created on your server. It contains the log of the occurred errors. <\/p>\r\n
