Fatal Error Recovery mode not accessible - dashboard not available

[dnewcomerdesign]

Hi,

A friend's wordpress dashboard is completely down, after an older plugin threw a fatal error. ​https://make.wordpress.org/core/2019/04/16/fatal-error-recovery-mode-in-5-2/#utm_medium=referral&utm_source=facebook.com&utm_content=social

The recovery link was not accessed quick enough, and I was not able to access the dashboard when clicking through, it showed an error message - "Recovery Mode not initialized." and the WP dashboard itself was broken and all links were locked down.

To make matters worst, I logged into her host (earthlink) and deleted the problematic plugin manually which did not cure anything.

Is there anything I can do from her host platform?

Here is the message she received for context:

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, New RoyalSlider.

First, visit your website ([site_url]) and check for any visible issues. Next, visit the page where the error was caught ([site_url]/wp-login.php) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can't access your dashboard normally, WordPress now has a special "recovery mode". This lets you safely login to your dashboard and investigate further.

[site_url]/wp-login.php?action=enter_recovery_mode&rm_token=y2Z5zzwM56bG9yAfzF62uB&rm_key=vpcGNn0kXaFNBzfjUdHJcA

To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.4.6
Current theme: Customizr (version 3.2.10)
Current plugin: New RoyalSlider (version 3.2.3)
PHP version 7.4.19

Hi and welcome to Trac!

Please use the ​support forums for help with individual sites.

I see the site is available to visitors after deleting the plugin, even if you still cannot log in to the administration.
