Install any extension and site crashes and goes into maintenance mode. please help


Problem :

Platform: magento 1.9


When I try to install any extension, my site goes offline (maintenance mode).



I’m installing them through the magento connect manager.


An example extension would be


I have some extensions previously installed.


I’m running  Magento CE ver. on an ubuntu LAMP machine.


I’ve tried removing any unused modules and clearing var -> cache


What should I do?


learn magento

Solution :

As to Magento Connect not cleaning up after install and getting a 503 error, that’s pretty standard with Magento Connect installs. Find the file maintenance.flag in your Magento root directory and delete it. ( you can use filezilla FTP client to delete maintenance.flag file)


The maintenance.flag file puts Magento into maintenance mode and stops access to the site during module installation so the installer scripts that run after module installation can have half a chance to run properly on a busy website.

  • I know this if off topic but I’m looking into starting my
    own blog and was wondering what all is needed to get set up?
