Unable to go to Facebook and Twitter on Google Chrome and Safari

[KevinNguyen2112]

Hi everyone,
I have been facing this problem after I tried to install Gba4ios with the date trick.
The installation was failed. So i switched back to the current time and date.
However, I'm now unable to go to Twitter and Facebook. It says DNS Lookup failed.
I can use the facebook app, but Twitter doesn't respond.
I have attached my screenshot.
Please help !
Thank you.
