[Plugin: Better Backgrounds] Plugin screens lists an error for every plugin when i activate this plu

Plugin screen lists an error for every plugin when i activate this plugin. disable plugin fixes issue. This was a great plugin. all the other that do this are like far too many wordpress plugins, it installs but the option doesn’t appear in dashboard to change settings its properly if at all. Got to be the most annoying issue in wordpress globally. ive just tried 5 other wordpress background scalers and non of them appear in dashboard anywhere after installation and i board submitting these tickets. at least if your plugin doesnt work please announce when you will fix it. You were the best plugin for this. but im lost now. please fix this.
thanks.
