Entering the ip of the pbx in the browser gives me this error. This morning I loaded audio files for entertainment in the conference. Then the error came out
Whoops \ Exception \ ErrorException (E_WARNING)
file_put_contents(): Only 0 of 189 bytes written, possibly out of free disk space
The pbx is loaded into a kvm on SeFlow and can be accessed by VNC or SSH. What files should I delete and how do I find them to solve the problem?
