I had same issue. It will work on local but to run on server you need to update schema version to your db. you will not use aspnetdb.mdf directly

you can find script for that and update with your DB. hope this can solve your issue

download this script from this link https://drive.google.com/file/d/0B2D0SiDP8hTFN2tDX04zYVp6OXc/edit?usp=sharing

now you need to add this to your config file

<system.web>
<!-- membership provider -->
<roleManager enabled="true">
  <providers>
    <clear/>
    <add name="AspNetSqlRoleProvider"
        connectionStringName="myportalconstr"
        applicationName="/"
        type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
  </providers>
</roleManager>
<membership>
  <providers>
    <clear/>
    <add name="AspNetSqlMembershipProvider"
        connectionStringName="myportalconstr"
        applicationName="/"
    type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0,           Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
  </providers>
</membership>

 <trust level="Full" /> 
  <customErrors mode="Off" defaultRedirect="home"/>
  <anonymousIdentification enabled="true"/>

  <profile enabled="true">
  <providers>
    <clear/>
    <add applicationName="/myportal"  connectionStringName="myportalconstr"     name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider"/>
  </providers>

</profile>
</system.web>
