Facebook posting issues

I have been using this app for about a week and posting daily to Facebook, it had been working great until about 4 days ago. For some reason when i try to post to Facebook now it is blank and will not post. It seems to be fine when its sent through an email just not through Facebook which is to bad because I really like this app other than this issue. I have not deleted the app yet with hopes this issue would be resolved, can you fix this?
