[TYPO3-Solr] Empty Host Parameter

[Hans-Peter M.]

Hi,

i have problem to install solr3.
The solr server is running. (http://xy:8080/solr shows "Admin core_en")

The Error Message in the Developer Log said: 
tx_solr_ConnectionManager::getConnection() called with empty host 
parameter. Using configuration from TSFE, might be inaccurate.

I have configured the following:

- Use as RootPage is enabled
- Domain record was created
- in Template Setup:
plugin.tx_solr.solr {
host: localhost
port: 8080
path = /solr/core_en
scheme = http
}


TYPO3 Version: 4.5.21
solr EXT: 2.8.0

Did I forget something?

regards
hans-peter
