I've tried to upgrade from 1.2 to 1.4 following the instructions and get an error on the first step. When installing com_comprofiler I receive the following error:
Installer - Error
Copying plugin files failed with error: Failed to copy file: /srv/www/htdocs/tmp/install_4d90ef0e1217d/index.html to /srv/www/htdocs/components/com_comprofiler/plugin/index.html
When I look in the components directory I don't even seen a com_comprofiler folder.
Any help would be appreciated.
