Hello, we apologize for the inconvenience you’re facing with the PHP warning. The error you’re encountering is related to an undefined array key, and it’s likely caused by a theme, plugin, or compatibility issue.
To resolve this, we recommend following these steps:
- Deactivate all the plugins and reactivate them one by one until you find the one causing the notice.
- If the issue seems to arise from another plugin, we suggest reaching out to the plugin’s support team for further assistance.
If you suspect that Rank Math is causing the issue, we recommend updating to the latest version of all the plugins and themes you’re using. Additionally, you can follow our troubleshooting guide here to determine if there’s a conflict with another plugin or theme.
If you still have questions or need further assistance, please feel free to contact our dedicated support team. We’re available 24/7, 365 days a year and we’re here to help.

I’ve tried all the methods, deactivating and activating plugins and themes but can’t find it. Only if the Rankmath Pro plugin is disabled will the error not appear
We are also having the same problem, seemed to have started more recently.
The issue is likely coming from the analytics front-end when viewing a page logged in as an admin.
Seems to be iterating over a list of keywords improperly within the analytics module.
@PrassEvo
I’ve edited the ranking_keyword_array_sort function within /wp-content/plugins/seo-by-rank-math-pro/includes/modules/analytics/class-posts.php
To the following:
public function ranking_keyword_array_sort( $arr, $arr_order, $arr_orderby ) {
if ( 'DESC' === $arr_order ) {
uasort(
$arr,
function( $a, $b ) use ( $arr_orderby ) {
$a_total = isset($a[$arr_orderby]) && is_array($a[$arr_orderby]) && isset($a[$arr_orderby]['total']) ? $a[$arr_orderby]['total'] : 0;
$b_total = isset($b[$arr_orderby]) && is_array($b[$arr_orderby]) && isset($b[$arr_orderby]['total']) ? $b[$arr_orderby]['total'] : 0;
return $a_total < $b_total;
}
);
}
if ( 'ASC' === $arr_order ) {
uasort(
$arr,
function( $a, $b ) use ( $arr_orderby ) {
$a_total = isset($a[$arr_orderby]) && is_array($a[$arr_orderby]) && isset($a[$arr_orderby]['total']) ? $a[$arr_orderby]['total'] : 0;
$b_total = isset($b[$arr_orderby]) && is_array($b[$arr_orderby]) && isset($b[$arr_orderby]['total']) ? $b[$arr_orderby]['total'] : 0;
return $a_total > $b_total;
}
);
}
return $arr;
}
The errors seemed to have resolved for now, I am sure RankedMath will have to issue a fix for this one.
In my updated function it’s just checking to make sure there are values within the array so that it doesn’t toss that warning.
Hope this helps!
Thank you, this is very helpful. Hopefully there will be an update soon to address this problem.
