white screen with WP 5

Hey there, @nimrod54!

That’s surely weird. We can’t replicate your issue, could you help us investigate by sharing your PHP output? A white page is often a way to hide from the public a PHP error of some sort – so I wonder if you could look into your PHP logs and share any errors you find there, after accessing your new/edit form screen.

Let us know your discoveries!

Hi there,
here is what I found in the php-errors.log after activating the Happyforms plugin,
hope this helps

[09-Dec-2018 10:28:54 UTC] PHP Fatal error: Uncaught Error: Call to undefined function register_block_type() in /path/member5/wp-content/plugins/happyforms/inc/classes/class-block.php:62
Stack trace:

#7 /path2/htd in /path/member5/wp-content/plugins/happyforms/inc/classes/class-block.php on line 62

if you need more info, just let me know.
Otherwise I will delete the website, I had it up for test only.

BTW, I use Happyforms plugin without any issue on 3 websites. All 3 sites are updated to WP 5.

best regards

Thank you, @nimrod54!

That’s super weird. register_block_type definitely exists in WordPress 5.0, and the fact that you’re running 3 websites without issues confirms that. It seems to me a cached error (this, or you’re not really running WordPress 5.0).

Are you running any caching systems on your server?

Let us know your discoveries!

you’re welcome

no, I don’t run any caching.
I think the issue could be caused by using the plugin “WordPress Beta Tester”. Everything worked fine with the different WP 5 beta versions until I updated to the released WP 5.

You should check to make sure that you did not inadvertently “update” to WP 5.1alpha. If Beta Tester was set for bleeding edge nightlies, using Update after the release of WP5.0 would install trunk. Trunk, currently 5.1alpha, does not currently have all the merges from 5.0.

Reinstalling 5.0 will likely be needed.

Ah, I see @nimrod54!

@afragen is right then. It’s still quite odd because recent WordPress RCs should include that function, but I second Andy’s suggestion of reinstalling 5.0.

Keep us updated!

Hi,
as I mentioned, I had this site up only for testing and planned to delete it after the final release of WP 5 anyway. I sent you the info about this issue just for you to check if you had to update your plugin.
As said, I have the plugin installed on 3 other sites without any issue.
Thanks again for the nice plugin.
best regards

Got it, @nimrod54!

Glad to hear it won’t be an issue for you. Thanks for sharing your experience, it’s been a nice way for us to double check that we’re in line for WordPress 5.0.
