Not able to Create/publish a page in newly configured website



As the servers are upgraded for my project, I recently restored my old website database to a new database in the new server and created the website using EPiServe deployment center.

After the site has been created, I can see everything is working fine, but I'm not able to create/publish any page.

Can you please let us know if I'm missing anything.

Many thanks.

Can you please add the error message (if there are any) from the log.

I guess that the problem is that the database and site are out of sync (new code with old database)

Make sure that the current language is selected as available lanaguage under "Available Languages" option in edit mode.

After I enabled the EPiServer Logs, I found the following log:

You have som problem with the postback that the IIS does not like, try to do like the errormessage say, go into the web.config and search for  and change it to  and see what is happening

Thanks for your reply Henrik.

I'm able to publish the pages now.

I never expected the EnableEventValidation stops the page publishing from EPiServer CMS.

Have a good day :)

There is a faq about it here:

Glad that it works
