Invalid response from server ERROR message

[ed]

Trying to add a user. Get error message: "Received an Invalid response from the server" then served a blank screen. Same with project profile:

​https://www.transitionnetwork.org/admin/user/user/create
​https://www.transitionnetwork.org/node/add/project-profile

This has also happened for a user trying to add a project.

Ed can add an event and blog post, ingredient, panel page.

Received an invalid response from the server.

I can confirm this problem, but I don't get a blank screen after the pop up -- I'm able to just click the "OK" link and continue to use the forms -- I have added a user to test this.

I can't see anything in the logs that might be related to this.

This is due to some shonky error handling by Hierarchical Select module that handles the region selector. I saw it a lot during the PSE build when I was doing development.

It's almost certainly related to #554 and the Redis password issue meaning the js/json was served slowly or badly.

I've cleared the caches and now cannot reproduce. It's a one-off IMHO - closing, fixed.

confirmed - thanks
