Error 500 Internal Server error when trying to add/edit CMS page

[infinitydesign]

Hi,

 

I have recently tried to edit a CMS page for a site that I am the administrator of, however I am presented with either a blank white screen or and internal 500 error.

 

I have tried editing both the php.ini and config.inc.php files to try and increase memory but I do not get anywhere with fixing the issue.

 

Prestashop Details:

Prestashop Version: 1.7.1.2

PHP Version: 5.6.31

Memory Limit: 512M

Max execution time: 0

Upload Max File size: 5M

 

Config.inc.php details:

ini_set('memory_limit' , '512M' );

ini_set('upload_max_filesize','5M');

ini_set('max_execution_time', '0');

 

php.ini file details:

max_execution_time = 0

max_input_time = -1

memory_limit = 512M

 

I have also tried to debug the error but nothing appears when I try to use debug mode. I have checked the php errors in the server account and found this:

 

[:error] [pid 25139:tid 140677694355200] (12)Cannot allocate memory: [client xxx.xxx.xxx.xxx] couldn't create child process: /usr/sbin/suphp for /xxxx/xxxx/public_html/kyqpc3fspzpxma9q/index.php, referer: https://www.domain.com/kyqpc3fspzpxma9q/index.php?controller=AdminDashboard&token=5ddb4415b596c96fdd21ebc3ee07bd25

 

Struggling to try and figure out what is going wrong and would very much appreciate some help.

 

Kind Regards,

Jack

The server is low on memory regardless of the memory_limit value. Ask the administrator.
