Serious problem with Forms Edit



I've been upgrading a Relate site to V7 and have hit a fairly major problem where forms edit will not work.

When selecting forms editing nothing happens and when selecting on-page editing I get the following error in Firebug:


Which when expanded shows an object reference error as follows:

When creating a brand new site from scratch I don't get this error, it seems to be caused by the upgrade.

The process I adopted was:

  • Copy site to be upgraded
  • Upgrade site, CMS, followed by Community - this was only done to update the DB
  • Create blank V7 site
  • Copy files from site to be upgraded to V7 site - templates only, no dlls or config files
  • Update config files as appropriate - point to upgraded DB, correct VPPs etc
  • Fix build errors (there were lots!!)

I'm guessing this is a config issue but would be grateful if anyone could provide suggestions. Has anyone encountered this before?

Thanks in advance,

Have you tried this?

I have the same problem and tried the solution on that blog, but no success.

I have the same probelm with a site I have upgraded from 6R2 to 7.5. I am not able to edit pages that uses the TinyMCE editor. I have also tried to access the page type from the administration and I get the error Mark A has posted.

I tried the solution Linus posted but it didn't solve the problem, but I did notice something strange. I have upgraded multilple sites the last month so I checked the database of one of the other sites. In this database the view mentioned in the solution Linus has posted 'VW_EPiServer.Editor.TinyMCE.ToolbarRow' doesn't exist. Instead there is a view called 'VW_EPiServer.Editor.HtmlEditorSettings' so I am wondering if I have missed a part of the upgrade process and therefore hasn't gotten the database into the right state?


Just restarted my local IIS and used a private browser to avoid chaching issues and now the site works! So the solution provided by Linus did solve my problem. I still question why I have different databases and maybe this should be looked into some more.
