I see, yeah you can delete the cache yourself as well (try this at your own free will- on our testing environment first) if you have the settings on to save the cache as a file on the server it’s here under the related “app”. This is not blessed by Epicor or anything, but I was desperate, and I deleted it because I wanted to see what would happen.
For example, imagine you were having the error with Sales Order Entry, you’d enter this folder and then delete the cache file…
SERVERDIRECTORY:\Epicor\Websites\ENVIRONMENTNAME\Server\Apps\MetaUI\Erp.UI.SalesOrderEntry\cache
