I have just recently upgraded a large site from Drupal 6 to Drupal 7. When I load up the site it doesn't load any theme at all. Even when I check the admin panel under appearance it shows the enabled themes, but nothing shows up at all, style wise. When I view the source, it isn't pulling in any CSS or jQuery files at all. Does anyone know how I would go about fixing this?
Also, I am receiving this error 'The specified file temporary://fileoR4rjt could not be copied, because the destination directory is not properly configured. This may be caused by a problem with file or directory permissions. More information is available in the system log.'
I thought it may have something to do with the tmp folder/file-system but I can't seem to get anything to work.
Any help would be great. Cheers.
