I was referring to you maybe having SharePoint 2010 or 2016 version installed on 2013, as the possible issue causing the toolbar.ascx error. What was causing the error?

As for the “A membership provider has not been configured correctly….” error, that happens when the FBA Pack can’t communicate with the membership provider db. This is usually a misconfiguration of the membership provider in the config files, or a permissions issue with the app pool user not having access to the membership database on SQL Server.

I am pretty sure it is 1.3.6 I’ve installed.

I fixed the problem on opening the user management page. but got a new problem. it says “A membership provider has not been configured correctly, Check the web.config settings for this web application.”

Are you sure you installed the correct version of the FBA Pack for SharePoint 2013?

Sorry, something went wrong
The file ‘/_controltemplates/ToolBar.ascx’ does not exist.

I tried reinstall FBAPack and as well as reset web.config and machine.config, but still doesn’t work. this impact we cannot manage the users, and webpart of new users creation is not working either. Only existing users can sign in.

We are using the SP2013, server os is 2012. any ideas?

What error message are you getting? Invalid username and password? User doesn’t have permission? Something else?

I have checked every reply on the comments section and you suggest to check Secure Token Service config when we are able to manage (create/edit/delete) users, from FBA pack running on SharePoint.

I have reviewed every config file for that service, and it simply does not log in the user on SharePoint.

What could it be. Thanks.

Your machine.config was filtered out. Is there any specific error message? Does it just not accept the password when logging in and everything else works? Are there errors in the sharepoint logs?

No it is not working for new users as well.

This is my machine.config

Does it work for newly created users? Unfortunately if the machinekey is not the same as when the user was created, you won’t be able to recover already entered passwords.

Yes Chris, The client is ok with this approach. I changed my web.config of all the web applications, Central Administrations, SecureTokenService and the machine.config, All of them have the same machinekeys. But it is still not working. Anymore advise?

Your help will be much appreciated!
