We have the problem that as soon as we want to add a profile in another language to an employee in WordPress and click on update, the following error message appears:
Error Details
An error of the type E_ERROR was caused in line 48 of the file __.php Error message: Uncaught Error: [] operator not supported for strings in __/acf-bidirectional-update-value.php:48
Line 47/48 of the file acf-bidirectional-update-value.php then contains the following entry:
// append the current $post_id to the selected post’s ‘related_posts’ value
$value2[] = $post_id;
We use WordPress version 5.3.2 and PHP version 7.1.33. We had already switched to PHP version 7.0 and 7.4, but this did not bring any improvement.
