CPANEL – Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server

cPanel

(XID h96ukf) Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server. Please transfer the domain to this servers nameservers or have your administrator add one of its nameservers to /etc/ips.remotedns and make the proper A entries on that remote nameserver.

Looks like we can disable this verification on CPANEL.

getcomposer – memory-limit-errors

cPanel

 

root@server [/home/domain.tld/www]# php ./bin/magento module:enable Infortis_Cgen Infortis_Dataporter Infortis_Infortis Infortis_Ultimo Infortis_UltraMegamenu Infor

Check https://getcomposer.org/doc/articles/troubleshooting.md#memory-limit-errors for more info on how to handle out of memory errors.
root@server [/home/domain.tld/www]#

To check the current memory_limit try

root@server [/home/domain.tlm/www]# php -r "echo ini_get('memory_limit').PHP_EOL;"

On WHM

Let’s increase it to 2G, for example.

Apache, cPanel, Linux, PHP

 

[Thu May 12 03:14:41.562083 2016] [core:error] [pid 25726] [client 68.71.XXX.XXX:44611] End of script output before headers: manage.php
