You’ll need to use ftp or your host’s file manager module to rename the directory:
wp-content/plugins/woocommerce
to something else, say:
wp-content/plugins/xwoocommerce
That will take WooCommerce out of play and get you running again.
As to why this has happened, it could be a number of things. 500 is not a specific error.
One possibility is memory. Do you know how much memory WordPress has? The default 40 Mb is not enough, try to set it to 256 Mb.

Once you gain access to the site again, after following @lorro’s suggestions above, I’d recommend testing for conflicts.
To do that you’d have to re-name the WooCommerce folder to its original name. Then, disable ALL plugins on the site. It’s very important that you deactive ALL of them.
Once they are disabled, enable only the WooCommerce plugin. Does it crash the site again? If it doesn’t, then it might be a sign that the issue is a conflict with one of your other plugins. To determine which one exactly, you’ll one to enable plugins one by one, until the error occurs again.

Hi @mjperezfcr
We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
Thanks,
Hi, thanks! I didn’t get a notification of your replies so I wasn’t aware. In the end, I did a rollback and haven’t tried to implement WooCommerce again. I will have in mind your recommendations when I do it again. Thanks!
