Images not uploading on Blog posts, ok locally.

I can upload images fine within my local dev site, but when adding them on the staging server the image starts uploading and then no thumbnail populates in the assets panel, Resources folder is writable, any idea what could be causing this?

Thanks

Diagnostics and template were taken directly from the staging server…
