CiviCRM Community Forums (archive)

I follow the steps of the guide in Joomla installation guide in http://wiki.civicrm.org/confluence/display/CRMDOC/Joomla+Installation+Guide
Installation was succesfull according to the installer, say thats all was ok.
BUT, when I try to access to CiviCRM in the administrator´s menu I only get a blank page (Like in a php error)

According to CiviCRM wiki the causes can be someone of this:
1. insuffient memory for PHP <<<They recommend 24, I set 64 mb>>>
2. directories not writable <<<All directories in cmod 777>>>
3. PHP script error, such as trying to include a file which is not present <<<I don´t touch the files, so I think this can´t be the problem>>>
4. path to CiviCRM files is not being set properly . <<<Checked and rechecked, I follow the comments of the file>>>

BUT, after check all the items of the troubleshooting the CiviCRM still don´t run, so: Suggestions? Answers? Clues? Ideas?

Thanks, sorry the language´s errors.
