My Joomla site situated on first machine along with a database on second.
I up-to-date the configuration.php parameters
However I got error saying an infinite loop continues to be detected.
I am running Joomla version: 1.7.3 stable.
Odds are it's a php error inside your configuration.php file - possibly passwords features a quote as well as other character than breaks the PHP - presenting a syntax error.
Like a quick test - you can produce a .php file (possibly test.php) which includes 'configuration.php'. Load your test.php file and find out when you get a mistake.
Alternatively - inspect your configuration.php file by hand to place the mistake. Should you edited it by hand you might have erased a semi-colon for instance.
Hope that can help.
