How does one update nulled version without breaking site
Very simple... but always backup first.
- Backup your SQL Database (either using phpMyAdmin or tools in your control panel)
- Zip up your existing WHMCS installation and store it somewhere temporarily, just in case you need to roll back (like I had to due to the Lagom Theme incompatibility)
- Upload the new WHMCS zip file to your web server
- Extract the files from the zip file OVER the existing WHMCS installation, this should replace files, but keep any additional content (such as KB files, attachments, logos etc)
- Visit your WHMCS website, but add "/install" at the end, which will launch the upgrade process
- Complete the upgrade
- Delete the "Install" folder
If you have renamed your /admin folder, then you will need to delete the version that you renamed, and then rename the new /admin folder back to the customised version that you had because a new one would have been created during the extraction of the updated installation.
Rolling back
If for any reason, you have problems or incompatibilities, then you will need to roll back. To do this,
delete the entire WHMCS installation from your web server and re-extract your old one that you zipped up in step 2.
You will then need to drop all the WHMCS database tables from your database server and re-upload them using phpMyAdmin or your control panel's tools.
Hope this makes sense!
