# Plugin Dev Help Debugging White Screen (Editor Fails to Load) / Blank Posts List

 * I have been adding Gutenberg extensions to a couple of related plugins, RSVPMaker
   and RSVPMaker for Toastmasters, and am seeing the benefits. However, I am currently
   wrestling with an intermittent bug that occurs only in a few circumstances but
   is proving very difficult to debug. I have seen some other posts about “white
   screen” problems, and I’m hoping someone who reads this will have seen something
   similar and will clue me in on what to look for.
 * The most puzzling thing is that on a multisite install, the error occurs on some
   subdomains but not others — with no obvious configuration differences between
   them. To my great frustration, it works perfectly on a subdomain used for demo
   purposes but not on the subdomain I’m using in production.
 * In these cases:
 * * The editor fails to load post content (a white screen is displayed with no 
   controls or content). No errors are displayed in the JavaScript console.
    * The
   post listing screen also comes up blank. The table listing the posts sometimes
   appears for a moment and then vanishes. I haven’t been able to find any CSS or
   JavaScript code that might be setting display: none. In this case, I have seen
   some errors on the JavaScript console but I have been unable to trace them to
   any issues with my code (error log listed below). * The issue seems to be related
   to blocks I have defined for use with the RSVPMaker for Toastmasters plugin, 
   used to define meeting agenda items. If one of these blocks is included in a 
   post (for my event listing post type), the post will not display properly in 
   the editor and the listing of event posts will also fail to display — but, again,
   I’m only seeing this in certain subdomains of a multisite install. In other circumstances,
   it works fine. * I am puzzled by why the content of a post would cause problems
   on the post listings page (if that’s what is going on) since it is a listing 
   of titles and metadata, not post content.
