Cloudways disables certain PHP functions by default for security. The tmpfile() function is one of these, and MainWP requires it for uploading plugins and themes via ZIP file.

When You Need This

Save changes

Click SAVE CHANGES. Cloudways applies the new PHP configuration.

​
Verify the Change

After saving changes, confirm tmpfile() is enabled:
1

Check Server Information

In your MainWP Dashboard, go to MainWP > Info > Server.
2

Review disabled functions

Look for tmpfile in the PHP functions list. It should no longer appear under disabled functions.
3

Test an upload

Optionally, test by uploading a small plugin ZIP file through MainWP > Plugins > Install Plugins > Upload.

​
If Changes Don’t Take Effect

If tmpfile() still appears disabled after saving:
  1. Clear any server-side caching in Cloudways
  2. Wait a few minutes for the PHP-FPM process to restart
  3. Clear your browser cache and check Server Information again
  4. Contact Cloudways support if the function remains disabled
