White screen when access

bigcat · 1 April 2016 10:23

Hi,

CentOS 7
SuiteCRM 7.5.3
PHP 5.4.16
Nginx 1.6.3

I try to install SuiteCRM to test it before to migrate from SugarCRM.

http://crm.example.com redirect to http://crm.example.fr/index.php?action=Login&module=UsersAfter but i have a white screen with no error.

PHP:
[spoiler]upload_max_filesize = 256M
post_max_size = 256M
memory_limit = 256M
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
display_errors = Off
variables_order = “EGPCS”[/spoiler]

NGINX conf.d:
[spoiler]server {
listen 80;
server_name crm.example.com;
root /var/www/html/suitecrm;
index index.php index.html;
location = /favicon.ico {
log_not_found off;
access_log off;
}
location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}
# Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).
location ~ /. {
deny all;
access_log off;
log_not_found off;
}
location / {
try_files $uri $uri/ /index.php?$args;
}
# Add trailing slash to /wp-admin requests.
rewrite /wp-admin$ $scheme://$host$uri/ permanent;

include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}[/spoiler]

NGINX nginx.conf specific configuration:
[spoiler] #keepalive_timeout 65;
types_hash_max_size 2048;
#Erreur 504 gateway timeout
keepalive_timeout 1200;
#Antity too large error 413

This bug seems similar but doesn’t help to solve my problem :

Could you please help me to find what is wrong with my installation ?

Switch from CentOS 7 to CentOS 6, solve the problem

shinyvictor · 8 April 2016 07:07

I had this problem tonight, and went through each of these to no avail. But I narrowed down the problem by looking at the error logs in my root folder.

I had no memory limit set in my wp-config.php file

Adding the line

/** Memory Limit */
define(‘WP_MEMORY_LIMIT’, ’64M’);

To the file and uploading it solved it. So maybe add this as another cause of WSOD?

A white screen usually indicates a fatal error so you want to either check your php error log or turn on php error reporting. This can be done by placing this line in your index.php file

error_reporting(E_ALL); ini_set(“display_errors”, 1); or doing it in your php.ini file.

Either way you need to see the error thats causing it to fail.
