Okay, looks like a new error in logs for the portal, due to preg_replace.
Type of error: General
8192: preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead
sources/subs/PortalBlocks.subs.php
Line: 2009
$data = preg_replace('~<\!\[CDATA\[(.+?)\]\]>~eu', '\'#cdata_escape_encode#\' . Util::htmlspecialchars(\'$1\')', $data);
Attaching the file for you.
