I used wamp to install Magento 2 but admin not working correctly, how can I fix it
windows is not supported for magento 2.3.
There's quite a few issues that make it stop working, that admin blank screen being one of them.
My advice is to install a virtual box ubuntu server vm, and run magento from there.
This is broken because the recent github commit:
Fix Saurabh Dwivedi:
Replace in the
protected function isPathInDirectories($path, $directories):
$realPath = str_replace('\\', '/', $this->fileDriver->getRealPath($path));
