[horde] Problems with upgrade since php7

[Ferdinand Gruber]

Hi,

I wanted to upgraded horde to the latest version using the command

    pear upgrade -a -B horde/groupware

Now I get a lot of error messages.

horde/horde requires PHP (version >= 5.3.0, version <= 6.0.0alpha1,

....
I think it has to do with the upgrade from php5 to php7

Please help!
