PHP Warnings at Kinsta

Support
#1

Hello,
I have a new WP install, and I am getting the following warnings

2025/10/31 16:21:23 [error] 63454#63454: *53266 FastCGI sent in stderr: “PHP message: PHP Warning: Undefined variable $content in /www/learn_871/public/wp-content/themes/pro/cornerstone/includes/views/partials/graphic.php on line 154” while reading upstream, client: 161.142.149.51, server: learn.com, request: “GET / HTTP/2.0”, upstream: “fastcgi://unix:/var/run/php8.3-fpm-learn.sock:”, host: “learn.com:23213”, referrer: “https://learn.com/wp-admin/themes.php”

I have uninstalled all plugins and cleared the cache. What am I doing wrong?

Thank you in advance.

Hello @Learnari,

Thanks for writing to us.

I have checked your website from my end and was unable to replicate the issue. Could you please try clearing your browser’s cache and check again? If the issue persists, kindly share the exact steps you take to encounter the issue so we can follow along and recreate it on our side.

Thanks

Hi @prakash_s
Thank you for responding. The error is not coming from WordPress but from Kinsta’s error.log.

We have cleared Kinsta’s cache, as well as the browser cache. We’ve even tested using different computers. Is there something amiss with graphic.php on line 154? Just checking the possibilities.

Hope you can advise the next steps.

Hello Erica,

Thanks for sharing the error message. It is actually a PHP Warning, which may not greatly affect your site’s performance and functionality. You can ignore it for now. Usually, this could come from null variables or undefined variables due to broken images, like what you have in your custom header:

Hope this makes sense.
