gpt4 API error after update

I have some problems:

1, I updated to latest version today and it gave error about gpt4 api

2, The bot reply text is gray

3, I want to change the Bot position, (specifically it will be higher than the default position) I have done it by changing the css in the plugin but it doesn’t work with wordpress custom css

This is the best GPT free plugin but I hope you can add a feature that allows me to create content on every page and every post.

The page I need help with: [log in to see the link]
