UI Builder hanging

[Admin CJ]

Is UI builder under some sort of maintenance? Since yesterday, 9/17/2026, I am unable to open the module. When I click Editor as it is published, it just hangs and never appears.

Hi @Admin CJ ,

Looks good to me - Is your UI builder up to date? can you try updating to the latest available version (Plugins> search for UI Builder)? if this persist in your customer instance - please open a ticket with SN.

Hope it helps!

Hi @Admin CJ 

Please repair or update the UI Builder plugin, then try again.

ahoy @Admin CJ,

is it a PDI or client's environment?

If a PDI, then you might try to log out, clear cache, log in and retry again.

If a client's env, you might do the same as above and eventually ask any of your colleagues to validate from their perspective. 

EDIT: I also don't think there could be any "global outage" of any capability such as UI Builder..
