Eggsbox 360 anyone?
I use the RIBnet iPhone app almost exclusively and the only time I get an error is if I have a dodgy internet connection. Some people have reported connection errors recently, so that may be connected, but I think that's sorted now.
I think that the only confirmed issue is the greyed out "Send" button which is solved by hitting "return".
As far as I know there is no significant problem with the app itself. If you are having recurring problems there are a few things you can try:
1 - Force the app to close: double click the home button to display the app switching bar, touch and hold one of the icons until they go wobbly and show an x in the corner, touch the x on the RIBnet app. Then restart it.
2 - Reboot your iPhone/Pad/Pod: hold down the sleep/wake button and the home button together and keep holding them until the screen goes black
3 - Delete and reinstall the app: on the home screen that includes the RIBnet app icon, touch and hold one of the icons until they go wobbly and show an x in the corner. Then touch the x on the RIBnet app and touch "yes" to delete it. Then reinstall from the app Store.
Please bear in mind that the app is produced by a third party developer (it's a white label version of Forum Runner), and that it's free and comes with no warranty! We'll always try to make sure that it runs as well as possible, but there's sometimes a limit to what can be done.
