I have the same problem as you guys. When accessing through phpMyAdmin, I get the
error. Programmatically accessing i get this error: "Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in xxxxxx on line xxxx....." .
I know that it's not a programmatic error because I haven't changed the code and has worked fine for the last 2 weeks.
The MySQL database server is down but it's a different problem now than it was 2 weeks ago. Their database seems to be down a lot and is really unreliable...
