Solved : Whatsapp Not Loading on iPhone
Step 1 – Update Whatsapp to latest version
I know, you also will be like me, who always keep their iPhone OS and all related apps up to date with latest version. If not, please upgrade to latest version of Whatsapp if it’s not loading. Any known bugs, might have fixed in latest version and it might start working for you.Step 2 – Restart iPhone
Yes, this is very basic step we all know
and I am sure you must have followed! Reboot or restart iPhone will
free up internal cache and memory and if the issue of whatsapp is
related to that, this step may help to solve the issue without going
further deep toward solution.
Step 3 – Reset Network Settings
Many times, due to changes in network
settings could lead some conflict with app configuration with phone. If
that is the reason your iPhone whatsapp is not loading any chat, you can
try to resolve it by resetting Network settings as shown below.

Step 4 – Restore using iTune
One of my friend suggested to take
complete backup of iPhone and restore using iTunes may help. Since, I
was desperate to start my Whatsapp back which has stopped loading on
iPhone 6; I decided to go with his advise. It took almost 10 minutes to
take full backup of my iPhone and then he suggested to restore as new
iPhone and then restore backup. So complete process took more than 45
minutes with no result. One can imagine my situation!
Step 5 – Whatsapp chat backup using Third party Softwares
I know, you must be thinking what’s this
third party software? Yes, there are couple of third party software
available online, which will help you to take backup only of specific
applications including whatsapp. I tried one of them; ofcourse that was
paid but one of my friend had the license and I thought to try with
that. It successfully extracted text chat history of my whatsapp, but
unfortunately it fails to extract media and attachment history.
Finally What Worked to load Whatsapp?
I was about to give up with my chat
history after hours exercise to try all possible ways to re-load
whatsapp on my iPhone. But then thought to Erase all content manually
(not using iTunes) and restore my last iTune backup. I now, technically
there is no difference if you erase content using iTune or manually from
iPhone. But somehow, when I erase content using iTune and restore last
backup didn’t worked. And when I did the same thing following below
steps, it did solved the problem.

After erasing and resetting all content
and settings, I connected my iPhone with laptop and iTunes to restore
last backup. It again took another 35 minutes or so and finally my
Whatsapp loaded successfully without any further issues.
Bonus Tip:
As soon as my whatsapp loaded, before
reading hundred of messages from many chats, I simply went to settings
and took whatsapp backup on iCloud
And decided to take it periodically without fail.
So, do it now, take whatsapp backup on
iCloud and feel safe as this is a common bug in iOS 9 when whatsapp
doesn’t load or whatsapp chat doesn’t load. If you have backup, you can
delete and reinstall application without much trouble what I have faced.

So, don’t be panic like me if your
whatsapp doesn’t load and stop working all of sudden on your iPhone or
any other mobile phone. Just, try all suggested steps one by one and I
hope it will be normal. If even after following those steps it doesn’t
load, you may have to wait till next iOS update or give up with your
chat history and reinstall whatsapp.
