Hi Thierry, thanks for the report!

The error means WordPress is checking the PHP version actually running your site against our `Requires PHP` minimum, and finding 8.1.34 — even though your O2SWITCH dashboard shows 8.4.21.

On O2SWITCH/cPanel hosting this is a common mismatch: the PHP version shown in your control panel may differ from the version assigned to your specific WordPress directory. To fix it:

1. Log into your O2SWITCH cPanel
2. Open **MultiPHP Manager** (under "Software")
3. Find your WordPress domain/subdomain in the list
4. Set the PHP version to **8.2 or higher**
5. Save and try installing the plugin again

If MultiPHP Manager isn't available, contact O2SWITCH support and ask them to set PHP 8.2+ for your WordPress install.

Note: we're also lowering our minimum PHP requirement from 8.2 to 8.1 in the next release, so this won't affect PHP 8.1 users going forward.

Let me know if that resolves it!
