Hello,

There is no restriction in code on the number of order items. If you are having such issue, please check your php configuration file (php.ini) for `max_input_vars` and set it to higher number i.e, 10000. You might need to increase `max_input_time` and `max_execution_time` too.

Okay. I just noticed that some of the pdf report download are not working.

Please let us know which one so that we can check and fix. Thank you

Some of the purchase pdf downloads under the list of purchase menu.
Ex: website.com/admin/purchases/pdf/2 returns a blank page.

The download pdf from purchase actions are working fine. I have just tested on demo.
