Blank pages because of long (session?) urls

[einarso]

Hi,
I am struggling with a problem on my site. It seems that when I arrive on the site, and choose a product directly from one of the highlighted/random products (the middle area), I get a blank page and a very, very long URL. One example of the URL is:
http://www.altikost.no/index.php?mai...evrcmj74kuser2

If I click the banner first, I am able to chose products from the front page at will - until my next session it seems.

Can anyone help me with this?

This is on php v5.5, correct?

And, you previously changed the length of your sesskey to 128, correct?

if you know the location of your php.ini, can you please post here the values for:
session.hash_bits_per_character
session.hash_function

I believe I am running php 5.3.15.

You are correct that I recently changed the length of my sesskey to 128.

Here are the full lines I can find in php.ini:

; session.hash_bits_per_character
; Default Value: 4
; Development Value: 5
; Production Value: 5

session.hash_bits_per_character = 5

session.hash_function = sha512

Could you go into your Zen Cart Admin ... and into the Tools ... Server Info ... and check the exact php version that shows?

What happens if you change the length from 128 to 255?

What happens if you change the length from 128 to 255?

...not very much I think. Site seems to work the same way.

Is this a clean install or an upgrade?

[einarso]

It is an upgrade, but it had been running without any problems for a year before I upgraded my server from Lion to Mountain lion and had to restore my database. See theses threads:

k,

I notice you have suhosin running. It may be having some affect, or not.

To see if it is.

can you edit your php.ini

and see if there is a line like

suhosin.simulation = xxxx

change the line to (or add the line if its not already there) to

suhosin.simulation = on

restart apache and try again

you can also get the same affect by editing the .htaccess in the root of your shop and adding this line

php_flag suhosin.simulation On
