Hi Japun,
I am on Windows 8 with a local installation of Moodle 2.6 and 2.7. I can run Elegance only with theme designer mode on. In a different forum I read the advice to manually trigger cron (Site administration -> Notifications and click on cron.php maintenance script).
My local installation is on Bitnami. In case you need to try it out, you can download the installation file HERE.
Regarding your server problem, I recommend the following steps:
- reboot your computer
- open File Explorer and go to xampp\ (you should see something that is similar to the screenshot below)
- double click on manager-windows or a similar file where you read "application" in the type column
- click on Manage Servers (2. tab)
- at the bottom of the new window, click on "restart all" and leave this window open
- open your Internet browser and start your Moodle installation
- if you see the error message again, you need to go back to the previous application (Apache Server) and click on restart again
Hope this works. If it doesn't I recommend installing the Bitnami-Moodle installation.
With kind regards,
Hartmut
