We are facing a strange issue in SiteEdit. All the editable components are coming with a red block icon instead of pencil icon and we are not able to edit any of the component. We have tried republishing the components and have also verified that the component exist on page (as mentioned in troubleshoot document).
We are using SiteEdit 2009 SP3 – Build 126.96.36.19926. We have applied all the hot-fixes for SiteEdit available on SDL Tridion World. Attached is the screen shot for the problem.
