wxHex Editor
Newer soft then bless hex with some new features it’s written in C++ and can be used on mac and windows also.

Installing mod_pagespeed on apache is simpler then on nginx, here we should build nginx from sure with mod page speed, I will write down how to do this on ubuntu but this may work on any other distro
cd ngx_pagespeed-release-${NPS_VERSION}-beta;
wget https://dl.google.com/dl/page-speed/psol/${NPS_VERSION}.tar.gz --no-check-certificate;
tar -xzvf ${NPS_VERSION}.tar.gz;
now we can download nginx configure and install it
after this you should have everything installed, but when we building nginx from source there is no upstart script, create file /etc/init/nginx.conf and insert this in it upstart script from nginx website
# nginx
description "nginx http daemon"
author "George Shammas <[email protected]>"
start on (filesystem and net-device-up IFACE=lo)
stop on runlevel [!2345]
env DAEMON=/usr/sbin/nginx
env PID=/var/run/nginx.pid
expect fork
respawn
respawn limit 10 5
#oom never
pre-start script
$DAEMON -t
if [ $? -ne 0 ]
then exit $?
fi
end script
exec $DAEMON
This is bug which mostly not allowing you to go to first page or use back button, in version 3.4 it’s fixed but if you want to make just fix of 3.3 version, this is how you should do it open file /libraries/cms/router/site.php now find this
When you understood that many email are not delivered in your inbox which are sent from (Hotmail,Google or custom server) first of all you must check logs whats happening, if dns is configured properly and you see “Could not complete sender verify callout” in your logs which you can check in whm “Email”->” Mail Delivery Reports ” then this is because of Sender Verification Callouts
Use callouts to verify the existence of email senders. Exim will connect to the mail exchanger for a given address to verify it exists before accepting mail from it.
we can fix it very fast just go to “Exim Configuration Manager” in WHM and search for “Sender Verification Callout” check off which by the way is default, click save and test your mails.
