I have installed a new theme and ever since my media library and set featured image interface have slowed down to a stop. Even become unresponsive. I can't seem to get an answer from the tech support of the theme (annoying!). Is it an issue with the theme or does this happen with many images in the library? Is wordpress set up to handle 60+ images in the library. I hope since people create blogs/sites to be portfolios constantly. Please help. I am at my breaking point. Need to get this site live and am not able to create portfolios/galleries.
