[TYPO3-install] Google Adservices linked Site can't be displayed: ERR_TOO_MANY_REDIRECTS

[armin otto]

Hi,

currently I am tasked to take care of a rather old typo3 website, where I am cautious about twiddling too much because it seemed rather unstable at times.

Anyway, I noticed that the site works alright, but if you google certain keywords and our site comes up as an ad ( not just a result), I get the message, that the site can't be displayed.
 
Chrome browser reports ERR_TOO_MANY_REDIRECTS and recommends deleting Cookies and allowing third-party-cookies, but that didn't help.

So I'm guessing it's something wrong with the server or the typo3 installation.

I checked the typo3 site structure and the site root was indeed a shortcut to another page. I converted the root to a page, flushed the cache and the site still works ... but I still get the ERR_TOO_MANY_REDIRECTS bug.

Currently, the behaviour is like this:

example.com/WRONG_SUB_PAGE
-> Page not found! (that's ok)

example.com/?gclid=google_adservice_code_stuff ( <-- that's the url that google generates and can't display)
-> ERR_TOO_MANY_REDIRECTS

example.com/?anything
-> ERR_TOO_MANY_REDIRECTS

So ... is there any way to order typo3 to simply redirect /? calls to the index page? 
I figure that should do it, but I don't know how.
