Hello Frank,
Thanks for writing in! Usually a crashed site or seeing the white screen of death is because there isa fatal error or simply you have exhausted your PHP memory limit. We recommend that you increase your memory allocated to PHP. To increase it, please edit your wp-config.php file and insert these lines:
define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );
You can add it before the line
/*That's all, stop editing! Happy Blogging. */
And if the error persists, I would recommend that you enable the debug mode instead. You can do this by opening wp-config.php and adding
define('WP_DEBUG', true);
/* That's all, stop editing! Happy blogging. */
When you revisit the page, you should have some error output describing the issue in more detail.
We would loved to know if this has work for you. Thank you.
