## ServiceUnavailableException: TypoScriptFrontendController {#serviceunavailableexception-typoscriptfrontendcontroller}

### addRootLineFields which are not available {#addrootlinefields-which-are-not-available}

Happens if you have set some additional fields in
`$GLOBALS['TYPO3_CONF_VARS']['FE']['addRootLineFields']` which do not exist in the
database table `pages`. Try to do a **DB COMPARE**.
If you got this error, check if you have defined non-existent fields in your
`$GLOBALS['TYPO3_CONF_VARS']['FE']['addRootLineFields']` configuration.

### TypoScript PAGE cObject is missing {#typoscript-page-cobject-is-missing}

In certain cases, it is possible that this error occurs, when the
necessary PAGE cObject (e.g. `page = PAGE`) isn't available with the
requested `typeNum`. Check if your TypoScript setup is completely loaded.

### TYPO3 4.7.x {#typo3-4-7-x}

#### Mountpoints and Shortcut Pages {#mountpoints-and-shortcut-pages}

[https://forge.typo3.org/issues/14351](https://forge.typo3.org/issues/14351)

If you have a shortcut page which links to "first subpage" and the first
subpage is a mountpoint, than you will run into this error.

Do not use "first subpage" if the first visible(!) subpage is a
mountpage. You can select the mountpage as shortcut target - just do not
use the automatic functions ("first subpage", "random subpage"...)

#### Realurl and Mountpoints {#realurl-and-mountpoints}

If you use realurl and mountpoints. It seems that RealUrl cannot/does
not remove the cache entries, if you change a mountpage to a normal
page. If you got this error, go to the mountpoint itself and remove all
cacheentries.

TYPO3 4.7.4, realurl 1.12.3
