Sams These are all issues that can be resolved:
My images don't load. Likely due to caching. If you add ?nocache to the end of the URL do images load? Have you enabled Leap and you also have another image optimization plugin you are using? This can cause compatibility issues.
I can't update posts. This is also likely due to caching. You can clear caching and see updated posts here - https://pubdash.ezoic.com/leap/caching
Very little revenue for the ads to be there at this point. Need new theme. A little revenue is better than zero revenue I would argue, but that's ultimately up to you as a business owner.
Please let us know if the suggestions above resolved the issues with images and posts updating.
