Canonical can not be seen on my site

We are sorry to hear that you’re having trouble outputting the canonical on a specific page using Yoast SEO.

Before we can move forward investigating the issue further, we’ll need to make sure that we are on the same page. Do you want to output a custom canonical URL on the page here https://kuponly.com/indirim-kodu/trendyol/?

We look forward to hearing from you.

We are still confused here. When you say add my other pages like this page rather than homepage, do you mean you want to add the front page https://kuponly.com/ as a canonical on the page here https://kuponly.com/indirim-kodu/trendyol/?

We look forward to hearing from you.

Thanks for your confirmation. Often, we see problems occur in combination with another plugin or theme. The fastest way to rule out any conflict, is to deactivate all non-Yoast plugins and switch to a standard theme like Twenty Twenty.

Please test this on your development or staging site, if you have one. If not, we recommend using the Health Check & Troubleshooting plugin. This plugin has a troubleshooting mode, which does not affect normal visitors to your site.

If you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts

If you do not feel comfortable to do this yourself or if this does not solve your issue, our Yoast SEO Premium plugin comes with one year of (technical) support.

We don’t think it would affect SEO and SEO settings as long as the canonical output is fine. We would suggest monitoring Google Search Console for any errors after the latest changes.
