Internal Server Error

I had no answer to my question and I saw other users with the exact same problem. Can you please offer a solution?

Most of the actions performed via dashboard return an Internal Server Error. When you enter the order, product, or whatever and does the change it works. Via dashboard, it crashes.

I wrote in the past to tell you that this new update you released was a total wreck. Very disappointing to see what happened to the plugin. It is full of erros now, barely working.
