What is a 503 error?
Error 503 (Service Temporarily Unavailable) usually means that you’ve outgrown your current plan and the resource limits provided to your plan have been reached. This will also be indicated in the Order Usage section of hPanel.
How to fix it
Depending on the type of resource, solutions do differ a little - all of them can be found here based on which limit was reached:

Exceeded inodes and disk space limits
If a 503 error appeared on your website, and the use of resources is small, it may be a matter of using disk space and/or inodes. You can check the disk usage by navigating to Websites → Manage, search for Order Usage on the left sidebar and click on it:

Delete all unnecessary files (cache files, duplicates, any old backup files, etc.). If you worry that you accidentally delete something important for the website to work, you can generate a backup in advance. You can also see which exact folders are generating too many inodes/taking too much disk space
Upgrade your hosting plan - with a higher hosting plan, you will receive more storage and a bigger inode limit
