Hi,
I have now tried mautic 1.2.1 on my webspace providing php 5.5.26 and apache, but I do receive an error 500 when first time calling index.php
I then have setup a LAMP-server (Ubuntu 14.04 based - turnkeylinux in use) as a VMware-instance, setup a VirtualHost on 8080 pointing its DocumentRoot to the mautic-directory (/var/www/mautic) and I also receive an error 500.
A short instrumenting of index.php shows that I got on the screen:
Step 1Step 2Step 3Step 4
Code:
[index.php] require\_once \_\_DIR\_\_ . '/app/AppKernel.php'; //require\_once \_\_DIR\_\_.'/mautic/app/AppCache.php'; try { $kernel = new AppKernel('prod', false); printf("Step 1"); $kernel-\>loadClassCache(); printf("Step 2"); //$kernel = new AppCache($kernel); printf("Step 3"); // When using the HttpCache, you need to call the method in your front controller instead of relying on the configuration parameter //Request::enableHttpMethodParameterOverride(); $request = Request::createFromGlobals(); printf("Step 4"); $response = $kernel-\>handle($request); printf("Step 5"); $response-\>send(); printf("Step 6"); $kernel-\>terminate($request, $response); printf("Step 7"); } catch (MauticCoreBundleExceptionDatabaseConnectionException $e) { define('MAUTIC\_OFFLINE', 1); $message = $e-\>getMessage(); include \_\_DIR\_\_ . '/offline.php'; } catch (Exception $e) {

Could you check Mautic logs (/app/logs dir) and server logs if there is some error message which would tell us more?

The /var/www/mautic/app/logs directory is empty.
The apache-logs show:
`127.0.1.1:8080 192.168.10.180 - - [02/Nov/2015:16:29:42 +0000] "GET / HTTP/1.1" 302 556 "-" "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.80 Safari/537.36"

`
First, there is the redirection 302, and then the server error 500.
I dived a little bit deeper into the totally unknown debris of php-debugging and enabled in /etc/apache2/apache2.conf:
`php_flag display_errors on
php_value error_reporting 2039
`
Restarted apache and now I got for index.php:
code Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 262144 bytes) in /var/www/mautic/app/bootstrap.php.cache on line 2701

[/code]
This outcome let me increase the memory-size of the virtual machine to 1GB and got the same result.
I then increased the memory-size to 2 GB and again achieved the same error at the same point.
And yes of course, there is enough memory available:
`root@lamp ~# cat /proc/meminfo
MemTotal: 2061256 kB
MemFree: 1809356 kB
Buffers: 14680 kB
`
I then checked this allowed memory-size of 33554432 which represents 32M. And I found in /etc/php5/apache2.ini the entry:
`root@lamp php5/apache2# grep "32M" *
php.ini:memory_limit = 32M
`
I increased that to 64M and what should I say, the mautic installation started up.
Would be great if such kind of memory exhaustion errors would be checked. Especially during the installation phase. Additionally it would be worth a hint that could be given to rookies like me.

I’m sorry for your troubles. Hopefully, your investigation helps others. As you suggested, I added the warning message if the memory\_limit setting is lower than 128 MB. It will be available in Mautic 1.2.3:
