I've now spent two days on this, so I'm reaching the end of my rope. Any help or suggestions (or just friendly commiseration!) would be greatly appreciated.
I've set up a new Moodle (3.5.2) install on a shared hosting service (A2hosting). I used the cPanel PHPChooser tool to set the file size limit to 1GB, and the system does give me a max 1GB (or at least it says it does). I tried to upload a .mbz file of around 450MB, and it constantly times out every time. I thought it might be problems with uploading, so I set up Google Drive repository. I am able to use the File Picker to successfully transfer small files from GDrive, but it chokes on bigger ones - even a 65MB PDF produced the error "Cannot read file. Either the file does not exist or there is a permission problem."
I've asked for help from my hosting company, but you folks are nicer. Does anyone have any idea about what might cause this?
