For the second time on my web site, custom content and other modifications have disappeared from index.php.
Why would this be happening? I have this theme of several different sites and I don’t want to have to change them, but I also can’t keep having the content disappear.
My header image is also being removed.
Is index.php reverted to the default when Wordpress updates? All of my custom CSS in the Customize page is still there.
Thanks for your help.
