Activation
After installing and activating the Flat Theme module, you need to set it as the default customers theme from the Perfex CRM admin panel.
Enable Flat Themeโ
-
Go to Setup โ Settings โ Customers.
-
In the Default customers theme dropdown, select Flat and click Save.


-
(Optional) If you use caching (CloudFlare, Redis, Varnish, etc.), clear the cache and hard refresh the page:
- Windows / Linux:
Ctrl + F5orCtrl + Shift + R - macOS:
Cmd + Shift + R

- Windows / Linux:
-
Visit your client portal --- the Flat Theme is now active.

If you do not see "Flat" in the dropdown, make sure the Flat Theme module has been uploaded and activated in Setup โ Modules first. See the Getting Started guide for installation instructions.
Troubleshootingโ
| Issue | Solution |
|---|---|
| "Flat" not in dropdown | Ensure the module is uploaded and activated in Setup โ Modules |
| Theme partially loads | Clear all caches (server and browser) and perform a hard refresh |
| Old theme still showing | Check if a CDN or reverse proxy is serving cached content; purge the CDN cache |
| Styling looks broken | Verify that the module was uploaded correctly and all migrations ran successfully |
If you are using a CDN such as CloudFlare, make sure to purge the cache after activation. CDNs can serve stale CSS and JavaScript files, which may cause the old theme to persist.
