Hey there,

I have noticed I’m getting a PHP error and not too sure how to fix it, or the root cause. Last night I installed Rank Math and right after I updated WordPress to the latest version that just came out. I thought I would check with you guys first before I move onto my other plugins, only because this is the newest one. These are my errors I’m seeing.

[10-Nov-2023 04:54:31 UTC] PHP Warning: Undefined array key “host” in /public_html/wp-includes/canonical.php on line 704
[10-Nov-2023 04:54:31 UTC] PHP Warning: Undefined array key “host” in /public_html/wp-includes/canonical.php on line 715
[10-Nov-2023 04:54:31 UTC] PHP Warning: Undefined array key “host” in /public_html/wp-includes/canonical.php on line 718
[10-Nov-2023 04:54:31 UTC] PHP Warning: Undefined array key “scheme” in /public_html/wp-includes/canonical.php on line 739

Thank You,
Ken

Hello,

The issue does seem to be with Rank Math, If I remove Rank Math I no longer get that error message, I have also found many other people having the same issue as me with Ran Math – Example here – https://support.rankmath.com/ticket/canonical-url-help/

If I google this error, I see others with Rank Math having this issue.

Thank YOu

The only changes I have made to the site are to move from Yoast to Rank Math and update WordPress to 6.4.1.
The site and all current plugins have been the same for over a year without this PHP error showing up.

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.

Could you please share the PHP version you’re using on your site?

We have asked since we recommend updating your PHP version to PHP 8.0 because anything below that has reached its end of life:

Let us know how this goes.

Thank you.

Hey, Yes, I was using PHP 8.2 most the most part of the year, and before that was PHP 8.1 – I have never used 8.0 or anything below on this site.

The only thing different on my site is Rank Math and WordPress 6.4.1.
The site has been up for over a year using the same theme ( last updated in August ) same PHP version – the only thing I did was install Rank Math and remove YOAST and update WordPress – that’s when this error started showing up.

Any idea what to do with this error? I have a WordPress theme developer telling me the problem is with Rank Math and its not compatible with PHP 8.1 or 8.2. So I’m hoping there is a fix or I need to remove Rank Math and PHP 8.0 will not work as it does not support IonCube

Thanks,
Ken
