Error Message after Install of Display Monkey #80

Closed cwhitsbm closed 5 years ago

cwhitsbm commented 5 years ago

Hello,

I have recently configure DisplayMonkey and am getting an error on the management site when I open it.

Upon opening the home directory for the first time I am getting this error message:

Message | The cast to value type 'System.Double' failed because the materialized value is null. Either the result type's generic parameter or the query must use a nullable type.

STack Trace:

Solved... One of my emps did attempt the install before I took over. Apparently however he did not download the latest and greatest and did not save his download file. So when I took over and had to re-download the sql scripts, I downloaded the most current and that must be where the mismatch came in. Thank you for your help.

I have just installed my DisplayMonkey and when I browse to http://localhost/displayMonkey/default.aspx

I end up to following error

dm_error

... have been going back and forth installation tasks, but I am not able to find 'where I have made misstake'.

Any ideas, about the error. How to get this up and running

hi could you please start a new thread, as your issue appears unrelated to that of the OP, which is already closed. Thanks
