Typo3 backend looks broken after upgrade

Friday, February 4. 2011

I upgraded typo3 sources from typo3_src-4.2.12 to 4.4.8 recently and though I followed the steps described for upgrades it looked rather bad, especially the backend presented itself in quite a broken and unusable way. I was already pondering to roll back the changes but luckily then found an easy cure for the apparent illness:
just had to edit typo3conf/localconf.php to include

 $TYPO3_CONF_VARS["BE"]["compressionLevel"] = '0'; 

and all went back to nice & normal
