If your Magento Admin Backend is down by activated the magento compiler mode,
here some reasons and solutions.

A possible reason is an active compilation status, check it about the console/bash/ssh
and if it is active, Disabling Magento compiler when Magento Admin Backend is inaccessible / down.

The Solution to deactivate the compiler mode


    Check current compilation status

$ php -f shell/compiler.php — state
Compiler Status:          Enabled
Compilation State:        Compiled
Collected Files Count:    8764
Compiled Scopes Count:    4

    Disable Magento compilation:

$ php -f shell/compiler.php — disable
Compiler include path disabled

   Clear all compiled files

$ php -f shell/compiler.php — clear
Compilation successfully cleared

    Ensure that compiler is disabled now by checking its status:

$ php -f shell/compiler.php — state
Compiler Status:          Disabled
Compilation State:        Not Compiled
Collected Files Count:    0
Compiled Scopes Count:    0

   Flush Magento cache

Very often installation of new extensions with Compilation Mode enabled breaks your site. You cannot view the front-end and back-end. Nothing works. In this case the only solution is to disable Compilation Mode to get the site back to normal state.

1) Connect to your server using FTP Manager

2) Go inside „includes“ folder

3) Open the file „config.php“ for editing

4) Find the lines:


and comment them out:


5) Save the changes.

Now you can get into your back-end. If you need to enable the Compilation mode again you should use „Run Compilation“ button and NOT just enable it again (as it will break your site again). Running it will compile all new files correctly.

or the other way


delete includes directory or rename it to any other name (_includes.unused for example):

ftp :~> mv ./includes ./includes.unused

Flush Magento cache
