ASP conundrum (how to resolve)

Okay, so I'm using validation controls on a website

At first I was getting the classic error

 WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive). 

Didn't take much to fix that.

I added the following to my web.config file

<appSettings>
    <add key="ValidationSettings:UnobtrusiveValidationMode" value="none"/>
</appSettings>

However, now when I run my pages, my asp:LinkButtons don't work correctly, their code-behind doesn't seem to execute (it's a school assignment so I can merely alter them to anchors. Guidelines mandate asp:LinkButtons).

I tried

<appSettings>
   <add key="ValidationSettings:UnobtrusiveValidationMode" value="WebForms"/>
</appSettings>

But then I get the old error and my page won't load.

:/ I'm very confounded. What can I do?
