We face a issue with our Magento 2.3.4, we got a blank page error when we visit the frontend.

Already enabled ini_set('display_errors', 1); but still no error is displayed.

We got a debug.log file with the following errors: 

[2020-03-17 10:33:01] main.INFO: Broken reference: the '' element cannot be added as child to '', because the latter doesn't exist [] []

I already tried to remove all cache etc, but I can not find and solve this issue.

Any idea how to solve this?

  • @MohitPatel Thanks! I tried this, but that does not seems to work. But the issue is related to the compile. – JGeer Mar 17 '20 at 12:36

  • @MohitPatel Thanks! But we already run 2.3.4. for a while without a problem. This seems to be related to 2.3.3. Are you sure this edit is still necessary? – JGeer Mar 17 '20 at 12:42

  • @MohitPatel Thanks! I tried this, but it did not work, same issue. – JGeer Mar 17 '20 at 13:24
  • you should start disabling third party modules there is a good chance the problem is being caused by a module. I also found a similar problem being caused by enabling the move js code to bottom of page option. – paj Mar 17 '20 at 21:50
  • @paj Thanks! That's what I also thought, but that did not work. I disabled all modules and still faces the same issue. I can not really understand why Magento is not displaying any error to solve the issue. – JGeer Mar 18 '20 at 08:18

Try to debug in this class and see what elements it is referencing and then find those in your XML files - vendor/magento/framework/View/Layout/ScheduledStructure/Helper.php:184

  • Thanks! But how should we debug this and what should we change in this case? – JGeer Mar 17 '20 at 13:08
  • Put a xdebug breakpoint if you already have that setup. If not then try doing error_log(); or do echo; die; for the values - $structure, $key, $type, $parentName . $alias – Arif Ahmad Mar 18 '20 at 06:37

Try this

app/bootstrap.php

Replace #ini_set('display_errors', 1); To ini_set('display_errors', 1);

try this awesome solution. it works for me... https://magento.stackexchange.com/a/318528

in this solution, we need to change only one line in "Validator.php" file which is located at vendor\magento\framework\View\Element\Template\File\Validator.php

find the function which named "protected function isPathInDirectories($path, $directories)"

inside this function you will see following line...

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

you have to replace this line with below following line

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