version 2.80 installation issues

Hi folks,

When installing the version 2.80 I am getting the following error if database is already created:
"Sequence contains more than one element" and
If I select an option to create new database it creates the new database but gives the following error:
"Object reference not set to an instance of an object."

I have done some changes in Views and css only not in code anywhere.

What is wrong with the installation I don't understand.

Please help me asap.

Thank you

Hi,

You do the following steps before installing again?
1. delete the file "settings.txt"
2. create a new database.
3. install again.


If you want to install with an existing database, then edit the settings.txt

Thanks Mariann...

It helped me a lot... It worked...

Thanks a lott....
