Hi,
Yes, there is a way. You will need to open resources file and change/delete appropriate value.
You can find that resource file in
<web site folder>/CMSResources/CMS.resx. There, in the column "Name", you will need to find "
bizform.errorvalidationerror" and change text in the column Value (clear it) or delete it completly (please see attached screenshot).

Then you will need also to delete cache and maybe restart your application.
You can do it in Site Manager -> Administrator -> System.
Best regards,
Martin Danko
