Cannot activate plugin

Hello,

Thanks for reaching out!

I would suggest you perform a full conflict test. To perform tests without affecting your live site, you can use a staging site (your host might have that feature, but you can create it with WP Staging as an alternative).

Then, set your staging site’s theme to Storefront, disable all plugins, and try to enable WooCommerce again.

Let us know how it goes.

Hi,

I removed all plugins including the must-use and drop-ins ones, in a staging site:

https://undostaging.wpengine.com/shop/

The text tab in wp-admin/plugins.php now reads:

All (53) | Inactive (53) | Recently Active (2) | Auto-updates Disabled (53)

Theme also changed to Twenty Twenty-Two.

WordPress is updated.

Still, if I click Activate, the error will come up.

I found out that the errors also came up on some other plugins (but not all).

Another direction will be very appreciated.

Thank you.

Hello,

Could you please share a copy of your site’s System Status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.? Once you’ve done that, paste it here in your response.

Hi, I can’t activate WooCommerce.

Plugin could not be activated because it triggered a fatal error.

And here’s the error:

Hello @yofazza!

Thanks for the reply!

I can’t activate WooCommerce.

Plugin could not be activated because it triggered a fatal error.

Can you please remove your existing WooCommerce installation via FTP instead of through your WordPress dashboard? You can then try installing a new one and see if that addresses the issue.

Let us know how it turns out!

@tamirat22,

I was looking to set up SSH access to do that (to make it quicker) when I got notification from the host:

https://wpenginestatus.com/incidents/371898

I did some tests after seeing it and yes 99% chance it is caused by it. I waited and the issue resolved 3 hours ago. Reverted back to PHP 8 and seems like there’s no more problem.

I’m really sorry for all the troubles.

Thank you.
