I am using Joomla for my website administration and appeared to have encountered an error while configuring cache settings. I accidentially set GUI option from file to xcache and now everytime I try to do something a dialog box appears requiring my authentication but when I enter it nothing happens and it doesn't save my settings. How can I change the setting back to "file"? I don't really have my FTP cocnfigured yet and when I tried to do so, this xcache box appeared again and disabled me from saving my ftp settings. Is there any other way to get to php.conf file where I could change that manually? There has to be one.
Thanks for any help!
