if you search in google for fe:
silverstripe ?PHPSESSID

you'll find in 3rd result a link to
http://scb-judo.de/sample-blog-entry?PHPSESSID=286e901cb73dd0194b48e2371eff26d1

if you open this link in firefox, you'll see the same problem i've seen on my page.
(this one is not mine!)

XML-Verarbeitungsfehler: nicht wohlgeformt
Adresse: http://scb-judo.de/sample-blog-entry?PHPSESSID=286e901cb73dd0194b48e2371eff26d1
Zeile Nr. 71, Spalte 37:		<a href="/blog/?tag=blog&PHPSESSID=286e901cb73dd0194b48e2371eff26d1" class="not-popular">blog</a> 

it seems to me, that there should be no & and this should be replaced by
&
to be wellformed in xml.
btw: this link comes from using (a href="#") tiltle="")mytilte(/a) in the template i think...

but i'm wondering what that PHPSESSID= setting at all has todo in an ss-website.
is there a possibility to get that away from google-index?

is there a solution to get rid of this bug?

btw: if you look at this page in InternetExplorer, you can see how blog-comments without any spam-protection in ss would be.
aaarghhh...

This is a PHP issue: http://www.wesh.co.uk/helpdesk/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=13&nav=0,15

THX for the info, i'll give that a try.

Meanwhile i had the same problem, if i give back an url
from one of my DataObject-functions.
fe:

function GetGeoCodeUrl() {
  return "http://maps.google.at/maps?f=q&hl=de&geocode=&q=4400";
}

then i use this in my controller-template

  controller xxxx
    $GetGeoCodeUrl
  ...

this shows the same error as mentioned above.

so better is to code the & sign as it should be in XML!

function GetGeoCodeUrl() {
  return "http://maps.google.at/maps?f=q&hl=de&geocode=&q=4400";
}

maybe this thing was'nt too clear till now...
