## Occurrence in Frontend {#occurrence-in-frontend}

The page is shown without the common template but just with brown
background and the typical TYPO3 Error-Message: "Oops an Error occurred"
This happens even without realUrl. After deactivating a content element
with powermail the page worked again, but the desired powermail-form was
surly missing.

## Occurrence in Backend {#occurrence-in-backend}

Going in the Powermail-Module (Web -> Mails) and choosing Function-Check
I got the brown background with another Error-Message shown:

Cookie was not set since HTTPS was forced in
`$TYPO3_CONF_VARS[SYS][cookieSecure]`.

## Steps without Success {#steps-without-success}

-   Changing the version of Powermail is NOT fixing the Errors.
-   Uninstalling or deactivating realUrl is NOT fixing the Errors.

## Fixing the Errors and Misbehavior {#fixing-the-errors-and-misbehavior}

In the Admin-Tool set `$TYPO3_CONF_VARS[SYS][cookieSecure]=2` or
`$TYPO3_CONF_VARS[SYS][cookieSecure]=0`
