[Resolved] Save origin language give error when i'm having true/false fields

I'm sorry to hear that you encountered some trouble with this.

Unfortunately, I haven't been able to replicate the problem on my end.

Would you mind helping me out with this? I've included a link to the staging site in the following message so that you can activate and install anything you need if missing. Thank you!

Thank you for your feedback.

I want to clarify: were you able to replicate what you reported initially?

Please upload screenshots of the steps described in the previous message to help me better understand the problem.

Thank you for your feedback.

Could you please try the following workaround on your site and let me know?

Turn off "Keep repeater and flexible sub-fields in the same order as the default language." and update the post. If this is not the option then edit \plugins\acfml\classes\Helper\HashCalculator.php line 25 replace

return self::hashArray( $value );

with

return self::hashArray( (array) $value );

Please backup your database before making any changes. This should resolve the error you reported.

We have already reported it to our development team. If you do not want to turn it off, you can also apply the workaround by replacing the line of the code I shared above. This should do the trick as well.

Can you share the error you get?

You can enable enable the debug.log. You can do this by adding a few lines to the site’s wp-config.php file. With the error log enabled, you will see what the actual problem is.

To enable it, open your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

In order to enable the error logging to a file on the server you need to add yet one more similar line:

define( 'WP_DEBUG_LOG', true );

In this case, the errors will be saved to a debug.log log file inside the /wp-content/directory.

Let me know what you see after the debug mode has been enabled.

It seems unrelated to WPML. I suspect it should be a fatal error in the debug.log that stops the server and returns an internal server error.

I'm seeing the exact same error, caused by true/false fields. The solution posted by @Andrey to change the line 25 of HashCalculator.php causes a different line to fail, and doesn't seem like a solution. This is what worked instead:

Change line 17 of HashCalculator.php:

````
} elseif ( is_int( $value ) ) {
````

to this:

````
} elseif ( is_int( $value ) || is_bool( $value ) ) {
````

Tested on PHP 8.3 with WPML 4.6.10 and ACFML 2.1.1.

The HashCalculator was introduced in 2.1.0.

In the meantime I have downgraded ACFML back to 2.0.5, which doesn't have the HashCalculator and doesn't cause issues either.

Did the WPML team test true/false fields with ACFML? Because this case isn't handled in the if/else tree.
