Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site.In this case, WordPress caught an error with one of your plugins, Toolset Types.
An error of type E_ERROR was caused in line 325 of the file /var/www/web/wp-content/plugins/types/vendor/toolset/toolset-common/toolset-forms/classes/class.conditional.php. Error message: Uncaught TypeError: array_map(): Argument #2 ($array) must be of type array, null given in /var/www/web/wp-content/plugins/types/vendor/toolset/toolset-common/toolset-forms/classes/class.conditional.php:325

Hi there,

Would you please update Toolset Types to version 3.4.17 and see if it fixes the issue?

If not, kindly follow the steps below:

- IMPORTANT STEP! Create a backup of your website.
- Go to "WordPress Dashboard > Plugins" and deactivate all plugins except Toolset and Toolset add-ons.
- Check if you can still recreate the issue.
- If not, re-activate your plugins one by one and check the issue each time to find out the plugin that causes the problem.

Thank you.

Hi there,

Thank you very much this seems to be a compatibility issue that needs to be checked further.

Would you please provide a package of your website so that we can test it on our server for more investigation?

Please follow the steps below to provide it:

Thank you.

Hi there,

I see that it is stuck on 60% waited for a while but it is not changing.

I checked the WordPress dashboard and it seems the plugin works ok on PHP 8 may I know what are the steps that cause the error to show?

I do not see that error on the website

Thanks

[Christopher Amirian]

Hi there,

I meant the duplicator is stuck in 60% and not showing the website to be able to get it. But now we have another issue.

The WordPress email that you get does not tell WHEN the issue happens. By that, I mean what are the steps that cause the error so we do not know where to check.

I'd appreciate it if you can follow the steps below to enable the WordPress debug mode, then if the issue happens you will see when it happen and get back to us so that we can check:

Would you please access your website files and edit the "wp-config.php" file on the root folder of your WordPress installation and add the code below into the file:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', true );

Please add the code above the line below:

/* That's all, stop editing! Happy blogging. */

For more information:

I also made the previous reply private to hide sensitive information.

Thank you.

[rodneyM]

Thanks for that. I copied the 3 lines into the config file and then visited the site, from the past error messages I visited hidden link and I got the same email regarding the fatal error. The site continues to work.

Hi there,

Thank you for the information. I managed to use the All in one Migration plugin to create a copy of the website.

I checked and the same issue happens on my installation with PHP 8.

I reported this to the second-tier and waiting for their answer.

I will update you as soon as I have news.

Thank you.

[rodneyM]

Thanks, I am glad you managed to recreate the error and get a copy of the site.

[Christopher Amirian]

Hi there,

The second tier has an answer. The issue is happening with warnings in PHP 7.4 too, the issue is a Fatal Error in PHP 8 and the reason is:

If you check the custom field group assigned to the Band post type you will see that it contains a custom field “reference 1”, and if you edit it and look at the display conditions, it includes some bogus condition that is responsible for triggering the problems.

Delete the condition, the issue is fixed.

Please check the screenshot

Thank you.

[rodneyM]

Thankyou Christopher, I presume you meant Representative 1. I went into to that custom field and deleted the condition. Hopefully that will save the issue for now, I would never have found that on my own.
Thanks

[Christopher Amirian]

You're welcome 🙂
