I have installed the latest version of Joomla (1,5.9) and worked very well. I installed the latest version free of Artia Joomsef until there all right. I went to configuraciión comprehensive set some parameters to try and save the changes, bug me, from there I can not enter the frontend or backend. I tried several options, including uploading a new file. Htaccess or change your code for other instructions that allegedly fixed the problem but nothing happens. . .

Somebody help me before they may have to uninstall everything?

Thank you!
