How to solve blank issue of Magento 2.2.7 admin page:

You’ll find this code:

protected function isPathInDirectories($path, $directories)
 {
 if (!is_array($directories)) {
 $directories = (array)$directories;
 }
 foreach ($directories as $directory) {
 if (0 === strpos($this->fileDriver->getRealPath($path), $directory)) {
 return true;
 }
 }
 return false;
 }

Which shall be replaced by the following code

protected function isPathInDirectories($path, $directories)
 {
 $realPath = str_replace('\', '/', $this->fileDriver->getRealPath($path));
 if (!is_array($directories)) {
 $directories = (array)$directories;
 }
 foreach ($directories as $directory) {
 if (0 === strpos($realPath, $directory)) {
 return true;
 }
 }
 return false;
 }
