Hi @andrekadow
Thank you for your question.
For the problem, it related to the quota of request for your account.
Because, Google allows for 50000 request per month/per user.
So seem your website has high traffic, that is awesome!
Solution:
I put the cache function on plugin to reduce request to youtube server – helps you get out of quota limitation. Simple, just go to Cache tab on my plugin setting and turn on it. You can set timeout cache is 1 day.
For this time, you can get other API key from your other gmail then put into API setting on my plugin for continue working with gallery on website.
Hope that convenient for your plan.
