As envato don’t have a dedicated forum for their own website, posting it here and hoping this will get noticed.
Can you please replace reCaptcha on your log on pages to some other Captcha provider as it is nearly impossible to log in due to : “Invalid API parameter(s). Try reloading the page.” error. I am not the only one experiencing this so please sort it out!
This is a common issue with goodle captchas, so not sure why you are still using it.
