I have just been wrangling with phpMyAdmin and MySQL server on my Win8 PC IIS localhost (there was no connection between these, which I think was due to MySQL service not starting so I reinstalled MySQL and reran the config setup and reestablished a connection between them, which fixed that).
However phpMyAdmin advised an update which I did by overwriting the files with the new version and including the previous config file.
I now have:
The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated. To find out why click here.
PMA Database ... not OK [ Documentation ]
General relation features Disabled
Physical path C:\inetpub\wwwroot\phpMyAdmin\pmadb
There are a few google links on this same issue that I have followed that have helped me fix this (I should have spent more time googling before posting!). So to solve the problem I needed to create a phpmyadmin database and import create_tables.sql and assign a new user with full privileges and then uncomment the config.inc.php file at:
/* User used to manipulate with storage */
$cfg['Servers'][$i]['controlhost'] = '';
$cfg['Servers'][$i]['controluser'] = 'phpmyadmin';
and uncomment lines below
/* Storage database and tables */
$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';
I also needed to add some lines from the new version
There was a good link describing this I wanted to save but I had to clear my browser cache to reload localhost/phpMyAdmin and in doing so I lost my history & that link!
I know this explanation is not exactly described but I hope it may help anyone else who gets a similar issue after updating phpMyAdmin. I'm still not sure what all these features do but it is all fixed now, thanks!
