Thumbnails in front office deleted after regenerating images

[PrestaFanBoy]

Hi,

 

When I tried to regenerate the images, always it ended in 404 error though midway. So, for once I unchecked the option

Erase previous images.

o Later, I found some of the recently added product thumbnails are missing in homepage and categories page.

 

Im not sure why every attempt of regenerating thumbnails is resulting in 404 error midway.

 

Can anyone suggest where I should correct or is it related to site speed and performance thing.

 

Thank you.
