Error while custom changes in theme

Hello, after last update. 2.2.8 to 2.4.9, the subject envelope is presently vacant on the server.

I had some manual alters on the haseader.php. How might I add the equivalent alters once more? (I actually have a reinforcement with my code, don’t know how to alter the subject in this new variant, can’t find it anyplace)

Hi there

Making update on the modified theme is not a good idea, you need to restore your website from the server backup because there is no other way to get back your changes
