Laravel - Configuration and Environment

You ran php artisan key:generate but your app still shows an encryption error. What is the most likely cause?

AThe .env file was not saved or cached properly

BThe database connection is incorrect

CThe app key is too short

DThe PHP version is outdated

Step-by-Step Solution

Solution:

Step 1: Check .env file usage after key generation
After generating the key, Laravel needs the .env file to be saved and config cached or cleared to use the new key.
Step 2: Rule out unrelated causes
Database or PHP version issues do not cause encryption key errors; key length is managed by Laravel automatically.
Final Answer:
The .env file was not saved or cached properly -> Option A
Quick Check:
Save and cache .env after key:generate [OK]
