Any ideas. 2.30 nop

To find out what went wrong you need to turn off the custom errors mode.
1. Open web.config file
2. Find out the following line <customErrors defaultRedirect="errorpage.htm" mode="RemoteOnly">
3. Replace it with <customErrors defaultRedirect="errorpage.htm" mode="Off">

whoops, last project I forgot to turn off. Thanks
