This is the place to report bugs and get support. When posting in this forum, please always provide as much detail as possible.
Please do not report problems with a custom build or custom code in this forum. If you are producing your own build from the source code and have problems or questions, ask in the developer forum, do not report it as a bug.
When posting in this forum, please try to provide as many relevant details as possible. Particularly the following:
Windows 2008 R2 Server, MSSQL Version 10, MojoPortal Version 2.3.9.9, .Net 4.0
When I tell MojoPortal to create a new site, I get a error page that doesn't say anything useful. When I look in the Site List, the site appears in the list. So, did it fail to copy something or what? This didn't happen with 2.3.9.7.
Start with Basic Troubleshooting to find out error details.
