Error after going from PHP 7,4 to 8,0

I’d start by looking at line 50 of your wp-config.php file. I’m guessing you’re using something like:

define( ‘DB_USER’, ‘my_db_username’, true);

Since PHP 8, defining case-insensitive constants have been removed.

If you paste your actual line here, I may be able to give some more tips. (do not post any credentials, of course)

Line 50 in the wp-config.php file starts with this: define( ‘SECURE_AUTH_KEY’, ‘SECURE_AUTH_KEY’,

I have switched back to PHP 7,4 but haven’t resolved the issue with 8,0.

Hi,

It looks like your wp-config is using define(…) With the third parameter (either true or false), which is no longer a part of PHP8. You didn’t paste the full line, though, so it’s hard to verify.

If that line ends with something like
, true );
Or
, false );

You want to remove the true/false and the preceding comma.
But again, you didn’t paste the full line so it’s hard to know for sure. Good luck!

There isn’t a true or false after the preceding comma – just the Auth key number.

But it does have it twice. define( ‘SECURE_AUTH_KEY’, ‘SECURE_AUTH_KEY’,
I don’t write PHP so I am on unknown territory
But could this be the issue? Or is it supposed to looklike that?

> But could this be the issue

Wow, yes, I believe that is exactly the issue! I assumed it was a typo in your forum post.

So, by having that appear twice, you’re actually using ‘SECURE_AUTH_KEY’ AS the value for your key! (instead of the crazy long value that should come later)

The line should look like this:

define(‘SECURE_AUTH_KEY’, ‘some-big-long-thing’);

I just uploaded the corrected version and set the PHP to 8,0 now I have to wait about 20 minutes to see the result. Hoping this works!

So far so good!! Yeeah!
Thank you so much for your help!

Glad to hear it and happy to help. Cheers!

It’s working!
