## The PHP extension "apc" or "apcu" must be installed and loaded in order to use the APC backend. {#the-php-extension-apc-or-apcu-must-be-installed-and-loaded-in-order-to-use-the-apc-backend}

If you've gotten this error message

```
Oops, an error occurred!

The PHP extension "apc" or "apcu" must be installed and loaded in order to use the APC backend.

```

Then there are two methods, which will work.

1.  Install and configure apc on the server. Maybe APC is installed, but
    needs more memory.
1.  Goto TYPO3 *Install Tool* --> *Configuration Presets* and
    choose *Database cache backend* (or: something different then `apc`) and save.
