+# Resolving `django.db.migrations.exceptions.InconsistentMigrationHistory` Error
+
+If you encounter the error
+`django.db.migrations.exceptions.InconsistentMigrationHistory: Migration socialaccount.0001_initial is applied before its dependency sites.0001_initial on database 'default'.`
+while migrating, follow these steps to resolve it:
+
+---
+
+## Steps to Resolve
+
+### 1. Comment Out Apps and Middleware
+
+Open the **settings file** (`common.py`) and temporarily comment out the following configurations:
+
+In the `INSTALLED_APPS` section, comment out:
+
+```python
+'django.contrib.sites',
+'django.contrib.redirects',
+```
+
+In the `MIDDLEWARE` section, comment out:
+
+```python
+'django.contrib.redirects.middleware.RedirectFallbackMiddleware',
+```
+
+After updating the settings, save the file.
+
+---
+
+### 2. Roll Back the Problematic Migrations
+
+Run the following Django command in your terminal to roll back the `socialaccount` app's migrations to the start (zero):
+
+```bash
+python manage.py migrate socialaccount zero
+```
+
+This will unapply all migrations related to the `socialaccount` app.
+
+---
+
+### 3. Restore Settings
+
+After rolling back the migrations, revert the changes you made in `common.py`:
+
+1. Uncomment `'django.contrib.sites'` and `'django.contrib.redirects'` in the `INSTALLED_APPS` section.
+2. Uncomment `'django.contrib.redirects.middleware.RedirectFallbackMiddleware'` in the `MIDDLEWARE` section.
+
+Save the file.
+
+---
+
+### 4. Reapply Migrations
+
+Re-run the migrations step-by-step:
+
+```bash
+python manage.py migrate
+```
+
+This will reapply all migrations in the correct order, resolving the inconsistent migration history.
+
+---
+
+### Summary of Commands
+
+Here’s a quick list of the commands you’ll need:
+
+```bash
+# Step 2: Roll back socialaccount migrations
+python manage.py migrate socialaccount zero
+
+# Step 4: Reapply migrations
+python manage.py migrate
+```
