Same here..I fixed it by editing line 69: instead of
$doc->loadHTML('<?xml encoding="utf-8" ?>'.$block_content);
I added these around it:
libxml_use_internal_errors(true);
$doc->loadHTML('<?xml encoding="utf-8" ?>'.$block_content);
libxml_use_internal_errors(false);
Would be nice if this could be fixed in next update 🙂
