I have the same issue as this thread, but still not resolve my problem with their replies.
I upgrade from phpmyadmin 3.3.10 to phpmyadmin 220.127.116.11 but it get error:
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.
I have checked with:
1. chown -R webapps:webapps /var/www/html/phpmyadmin
=> No result, still the same issue.
2. Read the error log:
[Thu Sep 06 06:47:37 2012] [crit] [client xxx.xxx.xxx] (13)Permission denied: /var/www/html/phpMyAdmin/setup/.htaccess pcfg_openfile: htaccess file, ensure it is readable
=> this file does not exist in /var/www/html/phpMyAdmin/setup/.htaccess
3. I have tried to rollback to phpmyadmin 3.3.10 version but it does not work, still same issue.
Can I have some advise?
