DMARC doesn't work with php >= 7.0
If I want to add an DMARC Record to my zone the page doesn't refresh and ISPConfig isn't doing something. But in the logs I see:
mod_fcgid: stderr: PHP Fatal error: Uncaught Error: [] operator not supported for strings in /usr/local/ispconfig/interface/web/dns/dns_dmarc_edit.php:290
This is caused by new initalisation of this array for new versions of php (<= 7.0). It is needed to init the array $fo_rec = array();
instead of $fo_rec = '';
