Captcha gfx_check not working

At some point (way in the past - maybe 2 years ago) I disabled the captcha from my site due to some issue I was having with it.

We'll my site has now become the target of a POS spammer who keeps signing up new accounts (like dozens every day) and I'm having to manually purge them out.

I tried to reenable captcha by setting...

$gfx_chk = 3

for new users in config.php, but it doesnt seem to be working. I've also tried setting it to a value of 7 for all users, but I'm still not being prompted to enter the access code.

Any clue as to where I should check next?

Thanks so much

P.S.
I've checked the last_ip section of the database for all these accounts, and they always come back with a value of 0 - how is this person cloaking their IP address?

Do you get something that looks like a "broken image"? I don't know for sure, but it might be that the GD libraries are not installed (ask your host to enable them for you).

This might help.

Ghostgeek you need to check the behavior of the captcha with both browser IE and Firefox. Like many guys I had the same issue with this function. After I changed the code in the files the captcha worked only in IE and not in Firefox. But it was a good start. I checked then all files and indeed I found a blank line in mainfile.php. Afterthat it worked with both browser. Hope this helps. However, there are so many reasons for this issue maybe use the search function here and you ´ll find out how people solved this problem.

I've just been scratching my head for ages on this one. Using RN 2.10.01

Yes Susan. After ?> in mainfile.php. Once I deleted that then all worked fine. Thanks for the simple but utterly time saving fix. Smile
