Generating combinations results in 400 (Bad Request) error

[maw95]

Hello,

I have a problem with generating combinations on one of my sites - every time I try to generate them, there's a red error popup in top-right corner: "Can't update settings".

Error in the Chrome  console is:

"POST {back office url}/index.php/sell/catalog/products/1?_token=sORZZ_cpZHnCNZ04SH0C9NMNqkGEsMif3-u0mfkDwA4 400 (Bad Request)"

Ajax response (in 'network tab') is:

{"combination_12_attribute_ecotax":["This value should not be blank."],"combination_12_attribute_minimal_quantity":["This value should not be blank."],"combination_12_attribute_quantity":["This value should not be blank."],"combination_13_attribute_ecotax":["This value should not be blank."],"combination_13_attribute_minimal_quantity":["This value should not be blank."],"combination_13_attribute_quantity":["This value should not be blank."],"combination_14_attribute_ecotax":["This value should not be blank."],"combination_14_attribute_minimal_quantity":["This value should not be blank."],"combination_14_attribute_quantity":["This value should not be blank."],"combination_15_attribute_ecotax":["This value should not be blank."],"combination_15_attribute_minimal_quantity":["This value should not be blank."],"combination_15_attribute_quantity":["This value should not be blank."]}

Most interesting things here are:

- I've upgraded Presta from 1.7.6.3 to 1.7.6.8 - with no result

- There's PHP 5.6 on the server, but there are many other PrestaShop shops on this server - and combinations work there properly

- I don't try to make huge amount of combinations - it doesn't matter if I try to do 8, 4 or 2 of them - there's always the same error

- It doesn't appear to be browser issue - tried on Chrome, Firefox and Edge

 

Errors, form data and server information are on screenshots. Anyone can help?

Open your PHP/Apache error_log file
