1. Can you try to deactivate all other plugins, even if they are not security plugins, and try again? This is likely a security feature of some other plugin. Also, try with a different theme.
2. Also, you can try to assign the manage_wallets capability manually to your user or role. You can use any plugin, such as *User Role editor* or *Roles & Capabilities*.
3. Another thing you could try, would be to enable logging in WordPress, then attempt again the “Clera/refresh data now” button. Is there any error written out in the WordPress logs?
The fiat coin adapters are always shown locked by design. This is because there is no way to automatically run withdrawals. The plugin skips withdrawals from locked adapters.
Let me know if you tried steps 1,2 and 3 and what you found. Thank you.
