Cannot add to cart configurable product after migration - MAGENTO

Question

From 2 days I cannot figure it out. I tried everything and i was surfing in internet by hours... My problem:

I migrated Magento from 1one1 to ovh and after migration my products which are configurable (for example color to choose) dont want to add them to cart, products without configuration works fine. Adding is supporting by Ajax, and console turns: Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Andy ideas? :/ Maybe there are any important changes which I have to apply after migration?

Thanks for reply!

Answer 1

500 is server error. check server logs, what exactly happened. It may be even server ram problem, or to short execution php script time.
