Typo3 TYPO3\CMS\Core\Error\Exception "Warning: gzuncompress(): need dictionary"

Question

I'm working for the first time with Typo3.

Unfortunately I always get the error message:

#1476107295 TYPO3\CMS\Core\Error\Exception

PHP Warning: gzuncompress(): need dictionary in /var/www/html/public/typo3/sysext/core/Classes/Cache/Backend/Typo3DatabaseBackend.php line 157

I already tried to fix it like here and it seemed to work for a moment after a ddev restart but on the second click to edit the page, the error message was back.

Here are some Screenshots.

Maybe you can find my Mistake. Thanks.

Answer 1

In the installtool you can set the compression level for backend and frontend.
The values are written then to the file tyo3conf/LocalConfiguration.php and are these:

$GLOALS['TYPO3_CONF_VARS']['FE']['compressionLevel'] = 0;
$GLOALS['TYPO3_CONF_VARS']['BE']['compressionLevel'] = 0;

I added the value 0, so after changing the values you have to clear the cache and should be able to access everything again.
