[SOLVED] Installation Error

Hello,
I am trying to install Joomla 1.5. I have uploaded the files but when I tried to continue the installation by going to my site I get this error:

mark( 'afterLoad' ) : null; /** * CREATE THE APPLICATION * * NOTE : */ $mainframe =& JFactory::getApplication('site'); /** * INITIALISE THE APPLICATION * * NOTE : */ // set the language $mainframe->initialise(); JPluginHelper::importPlugin('system'); // trigger the onAfterInitialise events JDEBUG ? $_PROFILER->mark('afterInitialise') : null; $mainframe->triggerEvent('onAfterInitialise'); /** * ROUTE THE APPLICATION * * NOTE : */ $mainframe->route(); // authorization $Itemid = JRequest::getInt( 'Itemid'); $mainframe->authorize($Itemid); // trigger the onAfterRoute events JDEBUG ? $_PROFILER->mark('afterRoute') : null; $mainframe->triggerEvent('onAfterRoute'); /** * DISPATCH THE APPLICATION * * NOTE : */ $option = JRequest::getCmd('option'); $mainframe->dispatch($option); // trigger the onAfterDispatch events JDEBUG ? $_PROFILER->mark('afterDispatch') : null; $mainframe->triggerEvent('onAfterDispatch'); /** * RENDER THE APPLICATION * * NOTE : */ $mainframe->render(); // trigger the onAfterRender events JDEBUG ? $_PROFILER->mark('afterRender') : null; $mainframe->triggerEvent('onAfterRender'); /** * RETURN THE RESPONSE */ echo JResponse::toString($mainframe->getCfg('gzip'));

I have deleted all of the files, donwloaded the package again and uploaded them again, same message. Then I tried to install the files manually, but after completing all of the steps (before creating an admin to check the site), I still see the same message.

Can anyone help me here please? I don't know what I did wrong or how to fix it!
Thank you!!
