Okay Ehm1: Question
What did you use to re-upload your files with.

Yes I got the blank page too on the test page. Strange.

I'm sorry if I'm cross-posting or hijacking the thread. I can move my posts to a new one if that is the case.

Any way, I did the test and then I got a blank page.
No error, just a blank page.
I try with I.E. and Firefox and the same result. In both browsers I was log-in.

I'm sure is someting stupid I did when I re-install the softare... I just can't find what that could be.

Filezila.
PHP setup to ASCII
JPG setup to BIN.

I upload the fonts as ASCII then again as a BIN, with same results.

Just to confirm, you are running the test while being logged in as an admin correct? It will only display any output if so.

I have to take back my previous observation on the captcha test.
I had captcha disabled on my forum, so users can registry.
I enable and then I got a broking link sign on I.E.
and a blank page on Firefox.

If I click on the broking image, it shows no file name, but the PHP code.

Here is what should be in the captcha directory. And nothing else
Captcha CHMOD 755
Backgrounds/
Fonts/
indexhtml

Backgrounds CHMOD 755
background1.jpg
background2.jpg
index.html
Fonts CHMOD 755
bullpen_.ttf
eflb.ttf
index.html

Check to make sure only the index files are 0 bytes

Are you enabling it as GD2 or ImageMagick?

On the I.E. I was admin
on the Firefox I was moderator.

I log-in on Firefox as a admin and the same blank page, (no broking image) appears.

The broking image only appears on I.E.

GD2
