Hi,
Please allow me to offer some insights into your code. I see some things that might cause it to work differently than you expect.

First, the full version of the code how I suggest to implement it:
function redirect_to_welcome_page() {
if ( (is_page(‘welcome’) || is_page(‘contact’) || is_page(‘about_us’) || is_page(‘login’) || is_page(‘register’)) && !is_user_logged_in() ) {
wp_redirect(home_url(), 302);
exit();
}
}
add_action(‘init’, ‘redirect_to_welcome_page’);

The differences:
1. Your if() statement has a precedence issue. && has a higher precedence than ||, so your code works like this:
—
if ( is_page(‘welcome’) || is_page(‘contact’) || is_page(‘about_us’) || is_page(‘login’) || (is_page(‘register’) && !is_user_logged_in()))
—
And I don’t think that it is what you wanted. Hence the correction.
2. After the if() statement you put a semicolon. So, you conclude its execution without having it do anything if the statement is true.
3. the wp_redirect() function expects the redirect number as integer, so I removed the single quotes.

That’s it, I hope it helps you.

Hello. Sorry for the issues you are experiencing. I will explain: version 2.9.1, rolled out on 11.12.2018, introduced some breaking changes. The theme was completely rewritten, and a mechanism was established to help clients migrate to the new version. But now, 5.5 years later, this mechanism is not compatible anymore and doesn’t do its job. This update is technically as if you (almost) moved to another theme. We cannot assist you with the issues. The only thing you can do is restore your backup, create a staging environment, update the website there and rebuild everything that needs to be rebuilt. And then roll the new websites out. I’m afraid there’s no other way. Always updating the themes when a new version is out is important. This is how these situations can be avoided.

Hello. I’m sorry to hear that you are experiencing difficulties. Please send me private message access to your admin area by ticking the box “Set as a private reply”. FTP access would also be helpful. Thanks.

Hi Michael,
It isn’t any nuisance at all. I should have explained. This is exactly what I wanted to show. Take what you wrote, add a semicolon at the end, and add it where you want a line break to appear. And it will. Look at it as a functioning alternative to the br tag.

No problem. I’m happy to hear that removing Gutenberg solved all the issues. Have a great weekend.
