Error in downloading patient prescription

Hi,
In patient prescription tab when I click Download (PDF) or View Printable HTML I get this error:

404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.```
It was working fine until now.

I'm using OpenEMR v5.0.2 (1)
