multisite images not working anymore.

I installed this plugin around a week ago & I started having issues with my images not displaying on my subsites (multisite install).
I have since deleted the plugin but i still cant view my images on my subsites

Images will not display under “media library” or on the website for any subsites.
I can still see all the files inside a “blogs.dir” folder for the sub sites but the main site images are inside “media” folder
if i upload new images it still does not display them.

The main site remains fine with no issues & all images load ok.

I have looked at file permissions for the files & folders to confirm they are set to 644 & 755

Is there any file that the plugin could have changed to cause this?
Do you have any idea’s on what to look for?

Thanks,
