"cannot open the rich text editor" error on MS Sharepoint Site

If you are trying to edit a page on a MS Sharepoint site and clicking the “Edit Content” link yeilds a pop-up window that gives you this message: “cannot open the rich text editor”, there are two workarounds that may fix this.

First, try unregistering and re-registering the control dlls. Open a command prompt and type the following:

> cd C:\Program Files\Common Files\Microsoft Shared\Triedit

> regsvr32 /u dhtmled.ocx

> regsvr32 /u triedit.dll

> regsvr32 dhtmled.ocx

> regsvr32 triedit.dll

Then restart IE. If this doesn’t work, you can try adding the Sharepoint site to your list of trusted sites:

In IE, click Tools>Internet Options>Security Tab>Trusted Sites>Sites Button>Add

Be sure to uncheck the “Require server verification (https:) for all sites in this zone” checkbox if your site does not support SSL.
