Service Unavailable 503

    I’m developing on local machine. The local machine has:

    4 CPUs
    4G RAM
    50G HD
    Apache 2.4.7
    PHP 8.1 with Memcached 1.6.20
    It hosts around 10 WordPress projects. Because it’s all local, only the project I’m working on gets a very very low visit (when I refresh).

    The site (woocommerce installed) was OK this morning. I tried to update the woocommerce plugin using the admin plugin interface. The update failed without giving any error message. The site then shows 503 on all pages (including admin).

    I tried restart machine and it didn’t fix it.

    I then moved all plugins out of this project. The site works again but the front-end pages throw errors because it can’t find woo_ related functions which is very OK.

    I then copy the plugins back to the project one-by-one. When I copied the woocommerce plugin back in, the entire site went 503 again.
    So I remove the woocommerce plugin from the project and using the admin (works again) to fresh install a new woocommerce. The installation is successful BUT it didn’t ask me to activate the plugin after installation (Remember every time you install a plugin the button will change to blue and say “Activate”).

    I refreshed my front-end page and it shows products.

    Then I refreshed admin, it shows 503. Now I refresh the front-end pages, all show 503.

    Looks like I’m in a dead-loop now.

    Any help is appreciated.

    More info:

    My CPU load is around 25% while I heavily refresh the product page. RAM load is around 17%.

    I have another copy on another server with some outdated code (custom theme). I removed my local project and replaced it with the copy from another server. Then replaced the them files using local backup, problem solved. So I guess that the failed woocommerce update has some data damage in the database.
