# “Error establishing a database connection” while updating plugin

 * [5 years, 7 months ago](https://wordpress.org/support/topic/error-establishing-a-database-connection-while-updating-plugin/)
 * So I was updating the plugins of my site and “WP phpMyAdmin” was the last plugin
   being updated. It was taking a long time so I decided to leave it alone, let 
   it do its job and come back later to the page.
 * So I come back after an hour and its still stuck on the updating message. I visit
   the homepage and now I get a “Error establishing a database connection” message.
 * So I think maybe it’s still updating and leave it for another hour or so.
 * I come back and it’s still the same. I check the actual PHPMyadmin page and get
   this:
 * ———————————-
    phpMyAdmin – Error Error during session start; please check your
   PHP and/or webserver log file and configure your PHP installation properly. Also
   ensure that cookies are enabled in your browser.
 * session_start(): open(SESSION_FILE, O_RDWR) failed: Read-only file system (30)
 * session_start(): Failed to read session data: files (path: /var/lib/php/sessions)
   ———————————-
 * So I login to my server and find out I can’t access MySQL at all. MySQL has become
   read only.
 * I hope someone can help. Also, any ideas why this happened?
 * Thanks!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-establishing-a-database-connection-while-updating-plugin%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi.
    If you read the “Readme” page of this plugin, it says that once in a while
   people might experience quite weird issue, and this should be tested by the developer
   of a website. Even our plugin changelogs tell that there was no practical change
   during last versions (for which you were updating). I am just a maintainer of
   this plugin (and not PhpMyAdmin). What I can say is that this WP plugin has no
   relation to database, it doesn’t even fire a single DB query. It even doesn’t
   call PhpMyAdmin functions (unless you enter PhpMyAdmin page from WordPress dashboard).
 * Just to add 2 cents, you might need to contact the server administrator and ask
   to restart mysql instance. in case of VPS (linux,ubuntu, etc..) i might have 
   tried restarting services:
    `systemctl restart mysql` (or `mysqld`) and (whichever
   used): `systemctl restart apache2` `systemctl restart nginx`
 * if the issue will still persist, someone mentions this for specific folder to
   restore permissions: [https://stackoverflow.com/a/9579777/2377343](https://stackoverflow.com/a/9579777/2377343)
 * however, neither these can be called as my recommendation, instead these are 
   just my thoughts.

 * lastly, i advise not to keep plugin active when you dont use , and only activate
   it before using. So, you will be confident.
