I make changes to WordPress theme file and nothing happens

Question

I bought a WordPress template. In the footer, the template originally has this address:

I am trying to modify that address. In the WordPress admin section, I tried to achieve it by modifying the options.php file to have this:

All I did was to replace 28 JACKSON BLVD STE 1020 CHICAGO<br>IL 60604-2340 with Calle 4 Final, Colonia La Mascota <br>San Salvador, El Salvador. I clicked the Update File button and even logged out and logged in again in the WordPress admin system to confirm that the changes were applied successfully. In the admin section, I see the change to the address applied correctly but to my surprise, when refreshing the website, I still see the old CHICAGO IL address, not the new San Salvador, El Salvador address I want to have.

I was reading https://wordpress.org/support/article/i-make-changes-and-nothing-happens/#server-side-caching to try to figure out if this may be a server-side caching issue. I already tried loading the site from different web browsers and even visiting the website in incognito mode. I always see the old address. Any ideas? Thank you.

UPDATE 1:

Answering to cabrerahector's comment, this is an email I received from the hosting company:

Hello,

Thank you for reaching out to support. Some of our servers do continue Nginx, which does perform caching. However to be able to confirm whether or not your server is one of these servers, I would need you to verify the account. This is for the safety and security of your account. Can you please verify the last 4 digits of the Credit Card on the account or your Full AMP (Account Management Panel) Password? Additionally you may verify with the Customer or Developer Passphrase set up in your AMP. For additional methods of authentication please see the following guide.

If you want to modify the footer of your WP theme, you can edit the file called footer.php, which is inside the wp-content > themes > name_of_your_theme folders.
