I have a fresh install of V9.3.1 for testing and tried to install simple gallery from the market place.
I get the following error when downloading. Whoops \ Exception \ ErrorException (E_WARNING)
rename(): The first argument to copy() function cannot be a directory
I have a similar issue with the free ‘Lite Slider’. I’ve assigned it to a project and was prompted to go the dashboard to install. When I try to download I get ‘An error occurred while processing this request’.
@Steevb that sounds like it might be a different error. Can you check the logs to get the exact details of what the error was? If it is indeed the rename() function, this answer might fix it for you.
