Issue Unable to access WordPress admin panel

[DigitalSplendid]

Server operating system version

Ubuntu 18.04.4 LTS

Plesk version and microupdate number

Web Admin Se Edition

Yesterday, I noted that only the home page of workcosec.com is properly visible. If I try to access a blog post, there was a message of critical error.

Through FTP, I renamed plugin folder to plugins in order to disable plugins. Next, the blog posts then visible.

However, unable to access WP Admin panel.
Getting this message:

There has been a critical error on this website (https://www.canva.com/design/DAFRKs...share&utm_medium=link2&utm_source=sharebutton).

After trying to access WP admin panel through http://www.workcosec.com/wp-admin, I accessed error log. Showing Apache error: https://www.canva.com/design/DAFRLO...share&utm_medium=link2&utm_source=sharebutton

Help appreciated.

Seeing as this isn't really a Plesk issue, you might have better luck asking for help on WordPress Development Stack Exchange.
