Have you installed CumulusMX in C:\Program Files by any chance?

[dk6]

I am using Raspberry Pi software image!

[Mapantz]

Apologies. Selective reading this morning!

Did you start CumulusMX with the sudo command as it looks like you do not have the correct permissions to write a file to "/opt/CumulusMX/web/"? If you did I suggest you look at the permissions for "/opt/CumulusMX/web/" and add WRITE permissions to the directory.

As the supplied image was used, it sounds like the permissions in the image need fixing as well. @dazza Can you investigate?

is this ok?

from terminal i have this-->

what are the correct permissions?

[freddie]

Those permissions mean that anybody can create and delete files in that directory, which would not result in the error that you are seeing. The permissions are actually too generous, which is not always a good thing.

Therefore the permission issue must be related to the files within that directory. Could you supply a listing of that directory that includes the permissions? cd into the directory then use ls -l

Sorry but that is the same, Type in cd /run and then ls -l.

You have now listed the /run folder.

Try:> ls -l /opt/CumulusMX/web/

Urgh - symlinks You'll have to explain the purpose of those. Unless they are in the cmx image - in that case it'll be over to Dazza.
