We'd like to inform you that websites using PHP's 7.3 version are having technical issues resulting to a 503 Error. PHP 7.3 it's not quite stable so you should be aware before upgrading your website's PHP version to 7.3. We will make an announcement when PHP releases a new update, after testing it in our own test websites.
Note: As of now, we are aware that the issue only affects WordPress websites.
If you're facing the same problem and your website is down, you can easily resolve the problem by downgrading your website's PHP version from 7.3 to 7.2. from the Plesk Control Panel. If haven't upgraded the PHP version, you can leave this post.
As of now: The issue hasn't been resolved with WordPress sites running on PHP 7.3.
No new PHP version has been released. Check here for all the PHP releases.
Announcement (24/06/2019): Most plugins and themes have been updated to support PHP 7.3. While PHP 7.3 is still faster and most stable than PHP 7.2, please make sure that your blog can actually run the latest version of PHP. In case of any problems, please downgrade the version or take a closer look at your installed plugins and themes - some of them may not be fully compatible with the latest version of PHP.
