The database version '' does not match the project version '7.0', please check your connection strin

Run this query against the database and take a look and see what you're database says the version is.

SELECT *
FROM CMS_SettingsKey
WHERE KeyName = 'CMSDataVersion' OR
KeyName = 'CMSDBVersion' OR
KeyName = 'CMSHotfixVersion'

Secondly, you can check the version of your Kentico DLLs simply by going to the /Bin directory, right clicking on the CMS.CMSHelpers.dll and looking at the build version on the Details tab. Check to see the major version is at least the same as the major versions in the results of the query. My guess is they are not.

If it's the same, check the hotfix version. You can check in the file system to get this info to compare with the query. You can find the hotfix in /App_Data/Install/hotfix.txt.

There are a few things that could have happened:

• Wrong files were uploaded to Azure
• Your site is connecting to the wrong database
• Your site's dlls were not copied correctly or at all

These are just a few things I can think of off the top of my head that might have happened. Check what I've stated above and report back if you will.

Make sure you don't just hack the values in those keys, if your database structure doesn't match the version of DLLs, your data could get broken.

Hello Thanks for your help,

DB Query KeyName Key Value CMSDataVersion 7.0 CMSDBVersion 7.0 CMSHotfixVersion 76

DLL File Version 7.0.5165.22617

hotfix.txt 76

It seems like they match, I will look to re-upload the website files just incase something went wrong in the upload process

The application could not connect to the database, please check the connection string in the web.config file and SQL server availability.

Original error:

The database version '' does not match the project version '7.0', please check your connection string. 

So insure your connection to the db is getting through then. Seems this might be the problem if you're attempting to connect remotely.
