Parser Error Message: An error occurred creating the configuration section handler for system.data: Column 'InvariantName' is constrained to be unique. Value 'CoreLab.MySql' is already present.
This error hasn't occurred before.
I have not got a clue what is happening here.
I can deploy this application to the same host but a different URL and it will work.
Below is the web.config file I'm using:
***********************************
If then I get the following error.
This application was precompiled with personalization turned off, but it appears to have been turned on after the precompilation, which is not supported.
A well stated set of examples particularly wrt web.config configuration for Roles and Membership would be most helpful!!!!!!!
