So that’s not true, @averta and @skymen . Version 3.8.7 still breaks the Administrator pages when used with PHP 8.1.

I believe these errors are caused by calls with improper data to the functions in the wp-includes folder. Tried 3.8.7 but got the below errors and a blank page, so back to v. 3.8.1 again!

Thank you, guth!

It does! It is strange that Averta uses deprecated code in newer versions when they once made it right, in this v.3.8.1.

There is actually a new 3.8.6 version, but this also contains deprecated code so it breakes the administrator pages. So for now I will stay with 3.8.1, have deactivated automatic updates.

Hello tigere.

I ran the scripts inside this plugin through rector for php8.1 at https://www.phptools.online/php-checker and it proposed this changes in wp-rest-api-controller/admin/partials/settings-functions.php :

Maybe this would fix the problem?
I have not yet tried this plugin myself.

Could there be something wrong in rss.php in the includes dir, in the function fetch_rss(url)? The function does not return anything! Made some testing:`include_once(ABSPATH . WPINC . ‘/rss.php’);
$rss = fetch_rss(‘https://feeds.feedburner.com/joostdevalk&#8217;);
if ($rss == ”) {
echo ‘

• Flödet är tomt

‘;
}else if ($rss == 0){
echo ‘

• Flödet är noll

‘;

}else{
$items = array_slice($rss->items, 0, 2);
}
`
The url is correct – it works when I paste it into my beowser.
