Why am I not able to submit an Answer on the answer form?

Question

I am building a new website. On answer form, after submitting an answer an error pops up as:

"you are submitting too quickly, please wait a second. "

The hosting provider is not able to find out the reason why this is happening.
I did not submit any answer in my new website until now. Please help me.

Thanks

Can you post a screenshot? There’s nothing in Q2A that generates this message.

Is that CMS even Q2A? I don't see any Q2A parts in the website's structure.
It looks like WordPress to me ...
