The "issue" is that it takes a while to regenerate thumbnails, especially if you have alot of product and category images.


If your host will not increase the time, or perhaps you ran out of memory, then you just need to keep regenerating images until it completes. 

The first time you do it, tell it to erase all previous images.  However on the subsequent tries, do not delete existing images.


Eventually all thumbnails will be generated

There are 2 ways to solve the problem without access to the hosting configuration.

1) Repeat the regeneration after the 500 internal server error, more and more times, but untick the "delete previous images" option. Do it until you see the process is completed. It is a sort of brute forcing.

2) Use a module that fix the problem, also it has buttons to pause and resume the process (it worked for me so it is my choice), the prject is in GitHub: https://github.com/meetjey/imageRegeneratorPrestashop
