[SOLVED] Openstock errors

Hi,

We've recently moved to a new server and everything seemed to be working fine, however, any product that uses the openstock module for variations loses all images and changes after hitting save.

It works fine using the standard option module within Opencart 2.1.0.1

The only thing the error log says is:
2019-03-22 12:23:08 - PHP Notice: Undefined index: points in /httpdocs/public_html/vqmod/vqcache/vq2-httpdocs_private_html_oc_storage_modification_admin_model_catalog_product.php on line 169

2019-03-22 12:23:09 - PHP Notice: Undefined index: weight in /httpdocs/public_html/admin/controller/module/openstock.php on line 197

Now nothing has changed, it was literally copied from one server to the other so I'm at a loss.

Any help would be greatly appreciated.

Possible new server has php 7 version...

You can ask here..

It wasn't the php version surprisingly! It turned out to be a combination of a badly written vqmod and max_input_vars being too low (1000 not 30000).

All sorted now.
