FileZilla v18.104.22.168 on Win7, get the following error when launching:
Error loading queue An error occurred loading the transfer queue from \Data\settings\queue.sqlite3 Some queue items might not have been restored.
And get the following error when closing:
Error saving queue An error occurred saving the transfer queue to \Data\settings\queue.sqlite3 Some queue items might not have been saved.
I have tried clearing all databases within FileZilla, but I have not yet tried uninstalling and reinstalling FileZilla (need to make sure nothing needs to backed up first).
