In some cases Program The error prompt does not indicate the specific error location. If breakpoint tracking is used, we do not know where to insert the breakpoint. In this way, debug can only rely on speculation, for example, the following error prompt:
Error

Using this file, you can clearly see what went wrong:
- Download the dnndebug.rar file and decompress it to obtain the "dnndebug. aspx" file.
- Put this file in the root directory of the dotnetnuke website
- Then access the file in the browser (for example, http: // localhost/dotnetnuke/dnndebug. aspx)
- Enter the web contol address (for example :~ /Shorttopmodules/feedback. ascx)
- If you want to solve the problem, you can send an email to the author Nik to express your gratitude.
