Getting almost same error.

Unable to do anything from browser.

What can I do from back-end (Linux terminal)? Can I delete this trouble creating docType?

Error “On Frappe 14” is:

Traceback (most recent call last):
  File "apps/frappe/frappe/website/serve.py", line 17, in get_response
    endpoint, renderer_instance = path_resolver.resolve()
  File "apps/frappe/frappe/website/path_resolver.py", line 59, in resolve

Working on an experimental server, so can afford to experiments. Did:

From app/module/doctype:

mv personal_details ~/

From mariadb console:

drop table `tabPersonal Details` ;
delete from tabDocType where name like 'Personal Details';

Now getting error:

ImportError: Module import failed for Personal Details, the DocType you're trying to open might be deleted.<br> Error: No module named 'frappe.core.doctype.personal_details'

Frappe still recognises deleted “personal_details”.

How to update this information?

It may be wrong or risky way.

Any better approach may also be suggested.
