Hi
Can you show the "Web Hosting" witch all PHP version installed ?

To solve the problem I delete the old PHP and then install them again
 
Please try to toggle the installation:
Tools & Settings > Updates and Upgrades > add/Remove Components and select phpmyadmin
remove it
then install it again

Same here, there is no "phpmyadmin" option in the component list.

Has anybody found a solution ?
 
- how many mysql instances you are running?

I don't know, probably just one, as per default.

In any case, there's no way I'm reinstalling the whole system to get phpmyadmin back. I believe this problem happened after I ran the last Plesk update.

So, how can we reinstall phpmyadmin when it is not available anymore as a component in Plesk ?

Hi, for me the following solved the error:
mkdir /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/tmp
mkdir /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/tmp/session
chmod 777 /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/tmp
chmod 777 /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/tmp/session

I tried permissions 755, but it did not work.
 
I fixed it by opening my inspect window on Chrome while logged in to plesk, going to Application, and deleting all my Local Storage, Session Storage, and Cookies. You can expand them, right click on the correct domain and choose "Clear". Once I refreshed the page, it logged me out, and phpmyadmin worked again.
Antonio Cruz gave me the idea when he said it worked on Edge and not Chrome. I thought, must be something with old browser session storage or cookies from the earlier version of Plesk before upgrading.
 
I got the same problem today at
Plesk Obsidian v18.0.23_build1800200206.14 os_Ubuntu 18.04

for me the article from
Nov 11, 2018
solved the error:
mkdir /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/tmp
mkdir /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/tmp/session
chmod 777 /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/tmp
chmod 777 /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/tmp/session
