Can't see Admin Login Page in Magento 2.3 stable release

[vvasu001]

Check the admin page image for the issue. That's all I see when I go to localhost/magento/admin. Earlier, it used to show the login form. After this installation, it isn't showing anything. Any solution?

Tried removing pub/static files [barring .ht] and making Symlink to Copy, but nothing. I am also attaching homepage image.

Further the error I found in Google Chrome Console:

Refused to execute script from '<URL>' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
localhost/:1 Refused to execute script from 'http://localhost/magento/admin/admin/index/index/key/{Key here}/' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

Have you run a command?

You need to run below command from Magento root instance,

php bin/magento setup:static-content:deploy -f

[gelanivishal]

Hello @vvasu001,

Please setup developer mode on site and deploy static content 

php bin/magento deploy:mode:set developer
php -dmemory_limit=6G bin/magento setup:static-content:deploy -f

What is -dmemory_limit=6G ? I only have 8 GB RAM and 6GB Graphics Memory.

EDIT:

Here's the new error: Invalid Template 

[gelanivishal]

Hello @vvasu001,

That is memory limit, If you get any memory limit error then we need pass that parameter. 

Run below command in magento root directory

php bin/magento cache:clean
php bin/magento cache:flush
php bin/magento setup:upgrade
rm -rf pub/static/frontend/* pub/static/adminhtml/* var/cache/ var/generation/ var/page_cache/ var/view_preprocessed/ var/composer_home generated/
php -dmemory_limit=6G bin/magento setup:static-content:deploy -f
chmod -Rf 777 pub/ var/
php bin/magento cache:clean

I have same problem

It seems that you are using Windows! Magento does not officially support Windows.

This is not an official solution but can fix this issue for using Magento on a Windows machine for development and testing purposes.

1- Open this file:

vendor\magento\framework\View\Element\Template\File\Validator.php

2- Search for this line (around line 138 on version 2.3):

$realPath = $this->fileDriver->getRealPath($path);

3- Replace it with this line: 

$realPath = str_replace("\\", "/", $this->fileDriver->getRealPath($path));

This is a very common issue, Many people are not aware of the fact that Magento does not officially support Windows servers! some hacks and un-official modifications such as this one needs to be done in order to make it work on a Windows machine, If you visit the below link "Magento 2.3.x technology stack requirements" you can see that the only supported OS is "Linux x86-64".

https://devdocs.magento.com/guides/v2.3/install-gde/system-requirements-tech.html

I hope this helps and solves your issue.
