Something has happened with the Sellfire Plug-in to knock WP sites that have it installed offline - cannot even access Adm area.
It only displays this message:
Fatal error: Call-time pass-by-reference has been removed in /home/-------/public_html/wp-content/plugins/sellfire-affiliate-store-builder/sellfire.php on line 109
I've sent email to Sellfire support.
Does anyone have any info or understand this at all?
