osca

Hi, I know I am late to the party, but I came across the same issue several times. Solution: I increased almost all PHP-parameters for this operation temporarily to their maximum and then it worked. I don't know which of the following was the decisive one, but this is what worked in my case: memory_limit: 1024MB max_execution_time: 360 max_input_time: 120 post_max_size: 256MB upload_max_filesize: 256MB
