The last few weeks we have had a problem with OpenLP 3.02 where the uploaded osz file from Gdrive shows presentations/media with the dustbin next to them. I checked that the 'presentation plugin' is enabled, having sometimes got a message saying it had failed. It was enabled ok, so I re-installed OpenLP last week which appeared to cure the problem. It occurred again in Church this morning, however, which caused some consternation, however, we discovered that another earlier service would open ok , following which the intended file would also open ok..
I would be grateful for advice on what is causing the problem.
