Can you update to https://github.com/designcreateplay/NodeBB/commit/b8c089cfaa33a94dcd29bc33217fe58ab601c8b9 and let us know what output you get in console?

@baris

warn: Invalid meta tag.[object Object]
{ property: 'keywords', content: '' }
warn: Invalid meta tag.[object Object]
{ name: 'description', content: '' }

with the code:

console.log(tag)```

[baris]

Well an empty string shouldn't crash

tag.content = tag.content.replace(/[&<>'"]/g, function(tag) {
	return escapeList[tag] || tag;
});

Make sure you are on latest on both nodebb and the lavender theme. Are you still getting any crashes?
