Doesnt work for me

Hi,
I have a big site (37K pictures) and I’ve just changed my theme, I run the plugin for 24 hours and the result was 100% completed. But when I tried to open some posts I found that many image thumbnails are broken. Thus, I tried to regenerate each posts thumbnails separately but the result still the same. Also, thumbnails of the gallery are broken, but once I try to edit the gallery I can see the thumbnails clearly.
