Cannot instantiate non-existent class

[geras]

I installed Elxis but I cannot see the site. Appears  the  message:
Direct Access to this location is not allowed.Direct Access to this location is not allowed.
Fatal error: Cannot instantiate non-existent class: filemanager in ../includes/Core/loader.php on line 30

I have checked the rights of folders about writing. Any idea?
Thanks!!

which URL did you request?
did you check all suggestions in installation ?

1. If you can log-in in the back-end (administrator) of your site upload via your FTP the UpDiag tool and check your Elxis file system if all your files have been upload correct.

2. If you can't log-in in the back-end, check your file system manually or upload again you files.
2a. For installed Elxis do not upload the configuration file & the installation folder

3. Make 100% sure that all the files from the folder includes have been upload.
