Opaque White Screen Wordpress Migration Death

Question

My problem was that after moving the website to another server using the backup assistant, I came across a white screen of death.

I turned on debugging mode in Wordpress and still no errors, just a white screen.

So, I tried deleting all the files and reloading them again and leaving the database as it is (the one that BackupBuddy imported), but it still gives me a white screen.

So, I tried to trace the specific line where the white screen appeared, and got stuck in strange behavior.

In / wp-content / plugins / woocommerce / widgets / widget-init.php:

include_once('widget-cart.php'); include_once('widget-featured_products.php'); include_once('widget-layered_nav.php'); include_once('widget-price_filter.php'); include_once('widget-product_categories.php'); include_once('widget-product_search.php'); include_once('widget-product_tag_cloud.php'); include_once('widget-recent_products.php'); include_once('widget-top_rated_products.php'); 

• When I add "die (boom"); to "Include_once ('widget-price_filter.php');" = an arrow is printed.
• When I add "die (boom"); after "Include_once ('widget-price_filter.php');" = the arrow is NOT printed from.

So, is it possible to say that the error is inside widget-price_filter.php correctly?

The problem is that when I add a stamp at the beginning of widget-price_filter.php, it does not print it. This is similar to the line where the error occurred, nowhere.

What could be the reason for this?

Yes, completely (and you followed the correct debugging method).

The problem is that when I add a stamp at the beginning of widget-price_filter.php, it does not print it. This is similar to the line where the error occurred, nowhere.

If (as you say, you did), you added die('HELLO'); above (after <?php ), and it does not appear - this means that there is one of two problems

• File not found.
• Syntax error on this page.

You can solve one of three ways:

• Check php error logs (if you have access)

• Before you call include_one (in init.php), add:

   error_reporting(E_ALL); ini_set('display_errors', 'on'); 

• Clear the code completely (just leaving <?php die('HELLO'); ?> , Check if this appears, and then add the code in half.

If you have route 2, be sure to take it when you have work. Very important!

+1 for the actual time to try to solve it yourself before publishing (with echo and death). So I hope this helps with the rest.
