问题
I've inherited a skeleton Sitecore project based on Habitat (Sitecore 8.2 Update 6) but when I access the /sitecore url I'm getting the error:
Parser Error Message: Unknown server tag 'sc:PlatformFontStylesLink'.
In my folder serving the web site, I've used the web.config as supplied by a new Sitecore Instance Manager instance (this will be transformed by Habitat)
sc:PlatformFontStylesLink is a control Sitecore itself uses so for some reason it can't resolve the server tag. I'm guessing this is due to a configuration issue but Im not sure what exactly. The web.config includes this line:
<add tagPrefix="sc" namespace="Sitecore.Web.UI.WebControls" assembly="Sitecore.Kernel" />
回答1:
Check the version of your sitecore.kernel.dll. Likely it is incorrect.
I've seen that happen if a project in your visual studio solution is referencing the wrong version of sitecore - and "copy local" is set to true.
So to fix this:
- Restore the correct version of sitecore.kernel.dll t your site's bin folder (probably a good idea to check all your sitecore*.*.dlls )
- Find the offending project - update the reference - and set "copy local" to false.
Also - seeing that you inherited a Sitecore site, and are likely to have more questions down the road - thee is a more specialized Sitecore Stack Exchange site. you might want to check out.
