Cloned to new server, DB not allowing login

Hello, we have had to change our hosting from Fasthosts to ASPHostDirectory as the permissions Fasthosts were giving did not allow enough trust for the PDF export of sales invoices.

We have copied the files to the new hosting and exported the database from Fasthosts.

We have then uploaded to a new DB on the new hosting.

We have changed the connection string in settings.txt

We have changed the shop url in dbo.store table.

We have refreshed the app pool.

When viewing the new cloned shop, the site loads and the categories are shown. When clicking on login, the form is shown, however entering the old shops (ie the same credentials as the DB is the same) credentials, we get a generic error page. At present we have no way of accessing the backend.

Any ideas or last steps that we have missed?

Since you are facing the trouble while login, you'll have to find out the issue that's causing the problem. Because you are actually getting a generic error page (I presume of hosting provider's generic error page)

To see the issue, Edit your web.config file and find the element called customErrors and set its mode to Off instead of RemoteOnly.

Save this file and try to login again. You should see detailed error of the problem. Share the details so we can analyze the problem.
