  • let me know are u facing any problem with frontend? – Nagaraju K Dec 3 '18 at 11:54

It's causing you problem due to you are on windows.

Give a try to below workaround.

Find : /vendor/magento/framework/View/Element/Template/File/Validator.php:139

find : 
foreach ($directories as $directory) {
    if (0 === strpos($realPath, $directory)) {
        return true;

Replace with:
foreach ($directories as $directory) {
    $realDirectory = $this->fileDriver->getRealPath($directory);
    // and replace `$directory` with `$realDirectory`
    if (0 === strpos($realPath, $realDirectory)) {
        return true;



Its working for me too.

    @hiteshbalpande, I know its causing you a problem because You are on windows system and windows use '/' for seprator and linux uses '\' So if you are on windows than you have to do this. Its core bug reported on Git Also. – anonymous Dec 3 '18 at 11:34
