Resolving a critical error in WooCommerce
If your team has some technical capacity and you only need some information about getting back online, we’ve compiled some resources to help you with that.
#1: Disable WooCommerce plugin manually via FTP
Pretty straightforward to do: just head to your plugin folder via FTP and change the name of the WooCommerce plugin folder to something else, i.e. ‘0ld-woo’, ‘old-woocommerce’, etc.
#2: Disable all plugins manually via FTP
Similar to the previous strategy, just rename the plugins folder itself to disable everything.
#3: Revert to a backup
Hopefully, you’ve taken a full backup of your WordPress website before updating WooCommerce. If not, and if your hosting provider does regular backups, restore your site from the most recent backup prior to the update.
#4: Reach out to us for WordPress support and forget about it
If the issue is not resolved, and you don’t know what’s going on with it, this may be more technical than anticipated. At this point, you may need to contact an engineer or developer who can assist in resolving the issue quickly.
