Unknown server tag 'EPiServerUI:DynamicTable'.


I've just installed my first R2 site and have come across an error when accessing the UI/edit and UI/admin folders.

Description: An error occurred during the parsing of a resource required toservice

     your source file appropriately.

Parser Error Message: Unknown server tag 'EPiServerUI:DynamicTable'.

As far as I know all the correct assemblies are present and the asp account has access to them.

I've had this before with CMS 5 R1, but cannot remember how it was fixed.

Any one with an idea?

I also have this problem for a website.

I get this when I remove the virtual folders from web.config and simply just sport the folders directly in my webroot.

Make sure you have the correct assemblies referenced for the EPiServer prefix under <controls> in web.config for the edit and admin locations, for example:

<add tagPrefix="EPiServerUI" namespace="EPiServer.UI.WebControls" assembly="EPiServer.UI"/>

I have the same problem with a CMS 5 R1.

I have the correct assemblies referenced for the EPiServer prefix under <controls> in web.config

Any one with a solution for this problem?

Did you fix this problem? I am facing the same problem, if yes please let me know.

I had the same problem and it had something to do with the web.config. I replaced my web.config with the one from a default installation.

Check the ui path, so that you use the same all threw web.config

<add virtualPath="~/xxx/UI/"...

<location path="xxx/UI/admin">

Thank you Jesper ! Your tip save my problem.  

<add virtualPath="~/xxx/UI/"... from episerver.config didn't match up to element

<location path="xxx/UI/admin" from web.config.
