Uncaught error usually the pitching page

@joeworkman,

This was the original post, @isaiah thought that it might be a tcms issue

Why does the edit page sometimes expand

I have many stacks installed, my site uses Sitelok and Total CMS. Occasionally I see the following error which resolves itself and may be nothing at all to do with the issue? Fatal error : Uncaught Error: Class ‘Michelf\Markdown’ not found in /private/var/folders/kt/mbl6kcsj307bq346wpk3v3w40000gn/T/com.realmacsoftware.rapidweaver8/RapidWeaver/37848/document-0x7fcca1998ea0/RWDocumentPagePreview/Teachers/andrew/index.php:130 Stack trace: #0 /private/var/folders/kt/mbl6kcsj307bq346wpk3v3w40000gn/T…
