I've just recently been getting an error in my local installation on installed on apache on xampp. I'm running v4.0.5 of phpmyadmin. The error description is Error: Mismatch Token.
Has anyone else experienced this an found a fix for it?
You can try the following
Find the XAMPP php.ini file and uncomment by removing the semi-colon:
session.save_path ="/tmp"
Then restart apache.
Did you change anything in your apache server config files?
if not,
open browser, clear all history(ctrl+shift+del), and restart browser, go to phpmyadmin page.
it works for me :)
I too came across a same issue. I tried many ways, like clearing cache, managing more space for my /tmp directory. But at last I solved this issue by removing the unwanted files from my server & managing free space on my server.
You can check here how I have done that. Error: Token Mismatch PhpMyAdmin Cpanel Solved
Had the same problem. Solved it by changing following:
$token_mismatch = true;
to
$token_mismatch = false;
Changing session.save_path in php.ini to "/tmp" worked for me, RedHat6.
I had an extra "/" in my browser path. Removed that an it worked for me...
To resolve, try the following:
Delete cookies from 127.0.0.1.
Try to reproduce the problem in a different browser.
Does this help?
This error may appear if your website has a Content-Security-Policy header that is too restrictive.
This header caused the "Mismatch token" error for me:
content-security-policy: default-src 'self'; style-src 'self' 'unsafe-inline';
By adding script-src 'self' 'unsafe-inline'; the error disappeared:
content-security-policy: default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';
