php – phpmyadmin token mismatch for long time idle

Posted by: admin April 23, 2020 Leave a comment

Questions:

I installed phpMyAdmin 4.0.4.1 on my local develop enviroment, I set auth_type to config. Also I provide authentication requirements by this settings:

$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['password'] = 'somepassword';

But after a while that it is idle, if I click on any link of it , it shows me an error token mismatch, Is there any way that I increase its TTL? or make it alive permanently?

enter image description here

Above picture shows error.

How to&Answers:

I solve this annoying problem by following instructions below:

  1. open /etc/php5/apache2/php.ini
  2. find ;session.save_path = "/tmp", this line may look also like this ;session.save_path = "/var/lib/php5"
  3. remove first semicolon from this line
  4. restart apache by executing sudo service apache2 restart

FYI: I work under Ubuntu 12.04 with apache2, php5, phpMyAdmin 4.0.5 so for different systems and servers file path may be a little different.

In case of any troubles check if directory from step 2. is writable for server.

Good luck.

 /*

 if (isset($response) && $response->isAjax() && $token_mismatch) {
    $response->isSuccess(false);
    $response->addJSON(
        'message',
        PMA_Message::error(__('Error: Token mismatch'))
    );
    exit;
}

Answer:

For me this seemed to be caused by my root partition being full up, and I guess this error was triggered by php being unable to write to the session directory.

Answer:

I had to turn my cookies on in my browser and it worked for me. (Using MAMP on OSX)

Answer:

After doing all that was recommended here and in other places with no success, I found out that my /tmp was full.

To check it, just run from command line: df

It reports file system disk space usage.

Answer:

In my case I had to remove some files to make some space in this directory (\tmp) and the error was gone for now.

Answer:

Clearing your browser cache then it will work.

Answer:

To stop this issue, delete the “tmp” folder and make a new one called “tmp” or just clear the content.

Answer:

Try using another browser ex IE if it works then remove suspected chrome extensions .
Forr me pageXray was the problem.

Answer:

ISSUE RESOLVED –
I just cleared the browsing history and data for last 7 days. It solved the problem for me.
Try it.
