Hello Anil,
thanks a lot that you called our attention to this error. The reason for this is a typo in the file /var/www/pictory/php/deleteFile.php
We will correct this error in the upcoming new release of our RevPi devices. For now you can use the following workaround:
1. open a console session to your 'RevPi' device (login with user 'pi' and the individual password of your device)
2. execute the command:
sudo nano /var/www/pictory/php/deleteFile.php
3. change the statement beginning with:
if (count($arrPathname) == 2 && [...]
to
if (count($arrPathname) == 3 && [...]
4. Save your change by pressing 'Ctrl-X' and confirm with 'y' (for 'Yes')
After this, the 'Delete' Buttons in the file dialog window should work correctly.
Regards,
Frank
