 * Hi, [@natasza2023](https://wordpress.org/support/users/natasza2023/).
 * Glad you reached out.
 * The error message you shared with us are deprecation notices and warning, and
   even though they are disturbing, they should not affect your site’s functionality.
   Did you experience a fatal error? If you did, can you pass on the error here?
 * Also, you mentioned you use GiveWP add-ons. As the add-ons are premium features,
   we’re unable to provide support here. However, you can reach out to our dedicated
   support team via [https://givewp.com/priority-support/](https://givewp.com/priority-support/),
   and they will be more than happy to assist you.
 * We’re looking forward to helping you get to the bottom of this issue!

 * Hi there.
 * It’s been a while since we’ve heard back, and I know troubleshooting needs a 
   little extra time. I’m marking this as resolved for now, but if you still have
   questions, you can send them along right here, and I’ll be happy to hop back 
   in.
 * Have a great day!
