They all came thru - we have dealt with some server erros this week. But, any new post or PM that you try - if you get that error - it still works. The transition screen that brings you back is the problem.
I am currently looking into this problem. As it stands, PHP is up to date and the provider claims that they are not the ones to blame. I expect a call from the technical support in 2 days. They are reluctant to look at this, since it is not their software, however - they did something because our site was functioning properly.
