Login Fields clears before clicking login button

Hello,

We had strange experience with this plugin WP Fastest Cache-Free version. We had created new users in WP back-end and it was created successfully. When we login with that user id and click login button, the login id and pwd clears out. We created another user and same symptom. Our developer suspected and deactivated your plugin but success until we deleted the cache folder in the back-end. Then all worked fine for all new users. This is strange behavior of your plugin. In the first place, we don’t understand this behavior and secondly, it should delete the cache folder on deactivating.

We just tested free plugin first before buying the premium version. Please respond the cause of this login behavior.

Thanks
