TYPO3 Core

Hi Bernd,
you didn't submit much information about your setup. So it's hard to say whether you found a new bug or (what is more probable) you have an error in your setup.

Did you set TS conditions like [globalVar = GP:L = 1]? What did you define / change there?

Try to set "config.uniqueLinkvars = 1"

I tried to use config.uniqueLinkvars, but it didn't help. My setup using config is:

#####

config {
spamProtectEmailAddresses = 2
spamProtectEmailAddresses_atSubst = (at)
doctype = xhtml_trans
xhtmlDoctype = xhtml_trans
xmloprologue = none
metaCharset = utf-8

1. RealURL
   simulateStaticDocuments = 0
   baseURL = http://localhost/typo3/
   tx_realurl_enable = 0
   prefixLocalAnchors = all

1. Default-Sprache
   linkVars = L
   sys_language_uid = 0
   language = de
   locale_all = de_DE
   htmlTag_langKey = de-DE
   sys_language_overlay = 1

uniqueLinkvars = 1
}

1. English language, sys_language.uid = 1
   [globalVar = GP:L = 1]
   config {
   sys_language_uid = 1
   #sys_language_mode = content_fallback ; 0
   language = en
   locale_all = en_US
   htmlTag_langKey = en-US
   }
   [global]

Is this one still valid or solved for your setup?

That seems to be done. I rewrote the website, it is now working. You can close this issue.
