Suddenly shopware backend not loading

**Pupp3tm4st3r** · Jan 21st 2016

Hi there,

I´ve opened a thread some days ago but as this one is marked as solved I have to open a new one. We´ve got some serious error with our development server.
On the server there is one user with several subdomains (26 subdomains and 5 domain aliases). Today we deployed a shopware project and all of a sudden all shopware projects
won´t work? The frontend is accessible but the backend won´t load. It loads about 60 seconds and then breaks. Anyone ever seen that?

Today I changed from php-fcgi to php-fpm - no success

Any ideas whats going wrong?

Best regards
Simon

@Pupp3tm4st3r

When you post, don't forget to give us all information about your environment:

Distro, codename
i-MSCP version
i-MSCP server implementation for the service that cause problems (here PHP-FPM Apache2 httpd server implementation)
List of plugin in use
error log if any for the related service

And in your specific case:

PHP version in use (through phpswitcher or not)
PHP configuration level (per_user, per_domain or per_site)
Any exotic settings related to PHP and their values
List of any non-default PHP extension
Opcache/APC enabled or not

Thanks.

@Cool

You're too fast for me

PHPversion used depends on the shopware project - actual its a PHP 5.6.17, I didn´t configure the fpm pool at first, tried to raise the child processes, didn´t work, apache version 2.4.16.

The log now shows:

Failed to read FastCGI header

imscp version: 1.2.11
php-version used: 5.6.17
phpswitcher: 2.0.1
php-fpm
opcache enabld/disabled - no impact
apc not installed
ioncube installed (v. 5.0.19)

@Pupp3tm4st3r

In order:

Disable opcache/apc if enabled
Raise PHP memory in the pool conffile that belongs to your shopware PHP application

Once done restart the PHP-FPM instance that belong to PHP 5.6.17 (service psw-5.6-fpm restart if you use PHP as provided by PhpSwitcher) and see the result.

BTW: Still waiting your answer for what I've asked above

raised the memory to 256MB, no change

apc not installed, opcache disabled.

@Pupp3tm4st3r

Can I access the server?

mafioso · Jan 21st 2016

Your shopware is using the PHP version with installed ioncube loader? Also can you please post the PHP or JavaScript error?

**Pupp3tm4st3r** · Jan 21st 2016

I installed the ioncube loader as mentioned in the phpswitcher documentation.

Thats the only error I get: Failed to read FastCGI header

Nuxwin: Sure.
