[TYPO3-english] Everything got blank

[Guilherme Cateli]

Hi,

I was installing an extension on typo3 and after that, typo3 stopped loading and the website as well. When I tried to get access to the CMS, a fatal error message appeared about the extension, but now it doesn't happen anymore, showing just blank pages and I can't get access to install tool as well. Is there some way to restore typo3 without the install tool? I have the files backup. Thanks.
