After activation of Polylang plugin I got this warning. Tried looking around in support forums but without luck.
Does anyone know what this is about?

Warning: array_merge(): Argument #1 is not an array in /…mylocation on line 151

Hi,

Why did you stripped out the error message? As it’s just impossible to help.

I’m having similar issue.
This is what I get:

PHP Warning: array_merge(): Argument #1 is not an array in XXX\wp-content\plugins\polylang\include\filters.php on line 157

Line 157 in filters.php is:

$args[‘exclude’] = array_merge( $args[‘exclude’], get_posts( $r ) );

Hi,

This should be a conflict with a theme or a plugin. Could you tell me which one. It would help to test.

Also does it work if you replace the line with:
$args[‘exclude’] = array_merge( wp_parse_id_list( $args[‘exclude’] ), get_posts( $r ) );

I could create a test to reproduce it by myself. Fixed in the development version. You can download it from GitHub: https://github.com/polylang/polylang/archive/master.zip

Hello @chouby,
I have a similar issue here.
Message error is:

Warning: array_merge(): Argument #1 is not an array in /home/xxx/public_html/wp-content/plugins/polylang/modules/plugins/wpseo.php on line 32

The only .php where I see “array” is functions.php

These are lines 30 to 35:

// Register Primary Navigation Menu
register_nav_menus(
array(
‘primary_nav’ => ‘Primary Menu’, // You can add more menus here
)
);

Thank you in advance!

hi

I have a similar problem
Message error is:
Warning: array_merge(): Argument #1 is not an array in /wp-content/plugins/polylang/modules/plugins/wpseo.php on line 32

When I deactivated Yoast SEO plugin the problem resolved but when i activated it again i’m getting the same message error.

Thanks

Hi,

Same error here, conflict with YOAST SEO (disabling it make the warnings disappear).

More exactly:

Warning: array_merge(): Argument #1 is not an array in /XXX/wp-content/plugins/polylang/modules/plugins/wpseo.php on line 33

Warning: array_merge(): Argument #1 is not an array in /XXX/wp-content/plugins/polylang/modules/plugins/wpseo.php on line 33

Warning: array_merge(): Argument #1 is not an array in /XXX/wp-content/plugins/polylang/modules/plugins/wpseo.php on line 33

Here is the line 33:

$wpseo_front->options = array_merge( $wpseo_front->options, (array) get_option( $opt ) );

I’ll temporary disable Yoast SEO but your “magic” would sure be appreciated!

Not the same error. A different one introduced by Yoast SEO 7.0. This topic is more than 3 months old when this error appeared yesterday.
