Uncaught Server Exception after changing Module Name

Information about bug

I tried to change the name of Manufacturing to Operations and it threw up the following error:

Uncaught Server Exception There was an error building this page

I then tried to change the name back from Operations to Manufacturing and I received the error message listed below.

I expected to be able to change the name of the module without issue.

Hi @Seedthrower,

First thing, It's not a bug.

Changing the default module name in erpnext isn't possible because it's connected to a lot of code and some integrated structures. If you need to modify or enhance the base functionality, you can do so by adding it to a custom app. However, renaming the module can cause many functions to break, so it's not recommended.

migrate the site. If the migration works, great! But if it doesn't, you need to do a few things. First, make sure you back up everything (site). Then, create a new site and restore the database. Finally, double-check to make sure everything is working correctly.

Thank You!
