Thanks to those who have helped me so far. I have managed to install moodle 2.5 but I have now have a memory issue which I am talking to the hostserver about. I am also unable to locate any of my files within moodle. None of the images from my files are coming up anywhere on the site and I am denied permission to look at my private files.
I went into the config.php file to check that the dataroot path is correct, which it is. I did not change the location of my moodledata file and the config file is still pointing to the same location as it did before. What other possible causes are there? I triple checked the config.php file.
One more thing, I have not been able to check the upgrade notifications because of the memory issue. Would there be any connection or is that a separate issue?
Thanks for any advice.
Richard.
