You might want to consider changing your theme. Some themes have issues and that is because they are poorly programmed or they don't keep up to date with Wordpress updates. This is dependent on the theme owner.

My assumption is that if you choose a different theme and use that, these issues will likely stop.

You can change your theme at any time within your WP-admin:

Appearance => Themes

There are over 3,000 to choose from there and you will also be able to upload your own from there.

Simply do a search there (the search is pretty good) and you will be able to find a theme/look that you are seeking.

I have created some training on how to do this that you should check out: How to Change Your Website Theme in Wordpress

Hope you get your site up and running soon. Sounds like you have some bugs in the theme you selected. I google everything - check if there are any complaints about that Theme.

Good luck

good luck I hope you find your happy place to be patient
