How do I change a link on my WordPress website

OK. I navigated to the Appearance sidebar and I get the following:
https://www.tommach.com/wp-admin/themes.php

I can’t find where the Editor is.

There must be a sub-menu called “Editor” under Appearance menu.

When I clck on “Appearance” I get what you see when you open this URL:https://www.tommach.com/wp-admin/themes.php

I’ve searched this page thoroughly and cannot find “Editer” anywhere.

Can you provide a link to a screenshot of what you see?

It is possible for you to share a screen shot of https://www.tommach.com/wp-admin/themes.php

Also ensure you are logged in as Administrator.

Here it is… I can’t send you an attachment to this email, so I hope you can pick up this link.

https://www.tommach.com/wp-admin/themes.php

Please understand that we cannot see pages within your administrator panel. Can you instead link us to a screenshot of that section?

This is an easy screenshot-ing service: https://snag.gy/

I have uploaded screenshot where I marked the position of Editor menu

I wish I could send you as an attachment the screenshot of the Appearance page I have on my screen,but this reply form does not allow for an attachment. “Editor” does not appear under the list of items under “Attachment.”

You can upload image using https://snag.gy/ service and share the link here, so community can review it and try to solve your query.

Also ensure that you are logged in as Administrator.

My screenshot refuses to upload on https://snag.gy/ even after multiple attempts. Oh well! I’m stuck I guess.

You can upload the screenshot on your website from media section and share the link here.

Also if you have FTP details, you can make changes from there as well (download file, edit it and upload back to the server). Note: create a backup copy before making any updates.
