on my frontend. Typo3 error logs shows this error every time I reload the page. Can´t google up anything regarding this error
Core: Error handler (BE): PHP Warning: ob_start() [ref.outcontrol]: output handler 'ob_gzhandler' conflicts with 'zlib output compression' in /home/www/web400/html/typo3/typo3/init.php line 457
It´s on a shared hosting account. I got no access to apache.
Does anybody know how to fix that?
Typo3 provides GZIP Compression. This needs to be configurated for the specific Page you are using. If it worked before, maybe they changed (restricted) some settings.
However GZIP Compression is not required for TYPO3. You can reduce the Compression Level of the Website in /typo3conf/LocalConfiguration.php or typo3conf/localconf.php (depends on typo3 version). Sometimes its also defined in a File AdditionalConfiguration.php. You have to check these for the Compression Levels. There is one for the Backend (BE) and Frontend (FE).
If your Install tool works (www.yourdomain.com/typo3/install) you can also find this Setting there.
