[TYPO3] Nothing at all shows in FE

[Hans Kristian Lintrup]

Hi list. I've been struggling for the past 3 days with this problem, so 
any help is greatly appreciated!

I've installed the dummy site (FC Bigfeet) and TemplaVoilá.

The dummy site shows text in FE, but it has not been possible for me to 
make any pictures appear. Only the default images located in 
media/uploads/ is showed, when I opt out any custom images in the 
template for the root page. If I manually place pictures in the 
media/uploads folder and refer to them in TypoScript, then they appear.

I've tried to figure out the inner workings of Typo3 in order to decide 
where temporary files go. My guess is that my web hotel can't read some 
portion of the generated HTML and thus no output.

Then I tried to use TemplaVoilá. I followed the instructions given in 
the tutorial and everything in the BE worked as expected, but this time 
nothing at all shows up in FE. Not a single character.

Then I downloaded the TYPO3Winstaller and tried all the above and 
everything worked perfectly.

So: How where does the generated HTML pages go? What is it that can 
prevent typo3 from generating the code? Is there something about 
read/write permissions I am missing?

Any help will do - a link to any material describing it. I've searched 
through documentation and read a lot (!), but still I've been unable to 
solve this problem.

Thanks in advance!

Best Regards
