Hi Tom-
Thanks for reaching out, and I’m sorry to hear about the frustration with your images.
Having BoldGrid Inspirations active shouldn’t interfere with your ability to upload images or use a logo. Do you get any error messages when you’re uploading a new image?
You described that some images you previously uploaded are not showing up in your library. Sometimes, regenerating your thumbnails can fix that. You can accomplish that with the Regenerate Thumbnails Plugin.
In addition, since you’re using one of our Platinum WordPress Hosting partners, you can contact InMotion’s support department to take a closer look for you.
