[horde] Configuration problems

[Wolfgang Paul Rauchholz]

I run a CENTOS 7 server, httpd-2.4.6 and php71u
I installed via pear under /var/www/myserver/html/horde

I can access Configuration via http://my-server/horde/

Database tables were created via horde-db-migrate
[  INFO  ] Migrating DB up.
[  INFO  ] Current Horde_ActiveSync schema version: 23
[  INFO  ] Ending Horde_ActiveSync schema version: 23
[  INFO  ] Current Horde_Alarm schema version: 2
[  INFO  ] Ending Horde_Alarm schema version: 2

Trying to access the Configuration gives me the following error:
A fatal error has occurredsyntax error, unexpected 'new' (T_NEW)in
/usr/share/pear/Services/Weather.php:167

DetailsThe full error message is logged in Horde's log file, and is shown
below only to administrators. Non-administrative users will not see error

When running the test.php script I get he following error message:
