Magento site not working after upgrading extensions

问题

I upgraded all the extensions that were showing in Magento Connect. I am new guy in Magento. Before upgrdation site was working perfectly. I am using it on Linux server. My admin panel and website both are unble to load.

It is available here http://130.211.244.103/. I did a lot of googling , edited my index.php , increased the memory limit

ini_set('display_errors', 1);
ini_set('memory_limit', '1024M');
umask(0);

Kindly suggest me solution to this issue.

Edit : I checked my system and replace my files with new magento files. But now sudo service apache2 restart Job for apache2.service failed. See "systemctl status apache2.service" and "journalctl -xe" for details. . The system is unable to start apache

回答1:

try this:

1. goto "includes/config.php" and comment every line of code in it.
2. empty the "var/*" folder

Hopefully will work again.

Something useful in var/log/exception.log?

You can also go to your error folder and rename local.xml.sample to local.xml for direct error printing in your browser.

I would recommend to first update your extensions in your local testing environment.

Have you checked for compatibility of your extensions first?

After digging into magento and some of my server's command. I solved my problem.

Automatically apache and mysql server stopped and they were not responding. So, I completely uninstalled apache using

sudo apt-get remove apache2*

& Reinstalled mysql

• remove MySQL:

  sudo apt-get remove --purge mysql-server mysql-client mysql-common sudo apt-get autoremove sudo apt-get autoclean

• Then reinstall:

  sudo apt-get update sudo apt-get install mysql-server sudo mysql_install_db sudo /usr/bin/mysql_secure_installation
