Thanks for sharing your query with us here in the Shopify Community.
I can see you’ve already had some input from the Community here, who helped you find a solution, that’s great!
If you’re specifically looking to change some of the wording in your theme’s language that you previously edited, you can search for, find and change that text using the Language Editor in your Shopify admin.
Removing the ‘powered by Shopify’ text is a frequent step taken by new merchants, so we have outlined how that can be done here on our help site, which you might also find useful if you wish to find and edit this text again.
Let us know if there’s anything else we can help out with for your store at any point!
