How do I solve a 503 Service Unavailable error in Magento?
The exact error should look like this:
Service Temporarily Unavailable. The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
This error often occurs when something went wrong with an update of Magento. When this happens Magento places a file named maintenance.flag in the homedir of the website which shows the 503 error on your webshop.
In this article we’ll explain how to solve this issue.
Steps
Step 1. Log into the cPanel of your Magento shop
Step 2. Under category Files, click Filemanager.
Step 3. Navigate to the homedir of your Magento shop.
Step 4. Delete the maintenance.flag file
Step 5. Navigate to the var/cache folder of your Magento shop
Step 6. Delete all the caching files
Step 7. If you reload the webshop now, the error should be gone!
