Forbidden error when accessing Graph module

I installed EMONCMS on a local server. All is working well except when trying to access the GRAPH module form the main menu. When I click on view on a feed I can see the graph Ok.

When I click on graph in the main menu I get the following error:

You don’t have permission to access /emoncms/graph/ on this server.
Apache/2.4.18 (Ubuntu) Server at Port 80

Q: how do I fix this?

Much appreciated in advance !

Sorry, I’m not an emonCMS expert. Have you checked the permissions for that directory, and who the owner is?

Hi Robert, thanks for your comments! Yes, I looked at the directory settings… Issue is I am not certain what they should be… (!)

I compared them to other directories (dashboard, for example) and the settings differ between the two, but again, should the settings be the same?
