Question

I\'m a web dev rookie and I\'m hoping someone with more experience can help sort this out. I was ambushed by a MySQL upgrade.

Solved. Hopefully this helps someone else with similar problems, and eases a few migraines along the way. A week of sheer panic left me seeking divine intervention when all else had failed, so the big guy upstairs gets the checkmark for this one. :)

Cause: Re-installing MySQL and the .NET connector meant the machine.config file customizations were overwritten.

Solution: After the updates, make sure the following two changes are in place in the machine.config file...

(1)

<membership>
   <providers>
      <add name="MySQLMembershipProvider" **autogenerateschema="true"** ... />
   </providers>
</membership>      

(2)

<connectionStrings>
  <add name="LocalMySqlServer" connectionString="server=dbServer;User Id=myUserID;password=myPassword;database=myDatabase" />
</connectionStrings>

It was the second one that was tripping me up. During the reinstall the code had been changed to...

<connectionStrings>
   <add name="LocalMySqlServer" connectionString="" />
</connectionStrings>

...which is why the site was attempting to connect to the localhost, and why the user info in the web.config connectionstring was being ignored.
