wpmu dev being able to diagnose a white screening site

Hi,
Is WPMU Dev working on any methods to be able to diagnose a wordpress site that is white screening? I'm asking because the remote access will not work if a site is white screening.

    Hello Corn,

    I hope you're well today and thank you for your question!

    That "white screening" that you are referring to is commonly known as a "white screen of death" and is a quite common issue. There's no need for special tools, though reasons for it might be very different.

    Troubleshooting is nearly always the same though:

    - enable WP debugging via "wp-config.php" and see if there are any Fatal Errors; if there are, most likely they are descriptive enough to suggest solution

    - if that doesn't help, turning off all the plugins via FTP usually helps; then - after getting site back up and running - you would want to login to it as an admin and turn those plugins back on one by one; at some point site goes down again and you know that the last plugin that you enabled is causing the issue.

    - sometimes its just matter of too low WP memory limit but that's also usually connected to the type/number of plugins active on the site so either switching some of them off or raising WP memory limit helps

    If none of this works, there's no "algorithm" on what to do. In such cases we would need a full access to the site (including FTP, cPanel) and would need to "search" as it might be something in server configuration, a caching issue, some error in the code (for example a small typo in child-theme code that's just been customized by someone). It's more like a "detective's work" then rather than a ready to apply recipe

    Best regards,
    Adam
