Hello,

Please check server error log and let me know the error details so that I can suggest.

Thank you

hello thank you for your response , i am not getting any server error on pose screen when i tray to make payment and fish this sale system will direct men on this url(""http://shop.globalsts.net/admin/pos) where your demo one direct me on this ("https://sma.tecdiary.net/admin/pos/view/5"") and shows me print page

Hello,

I am not sure what is causing the issue. Did you check your server error logs?

If you need to enable app logs you can change `log_threshold` to 1 in `app/config/config.php` and the perform action again to reproduce error. Lastly check the latest log file in `app/logs/` folder.

For the after sale page, please check your post settings.

Thank you

thank you sir i have enabled app logs and now i see this error from server log error

I see the error on the query we are sending purchase_id but the database column is sale_id that is the issue let me confirm if i change this sale_id to a purchase_id would it effect other sides ?

thank you

Hello,

I have checked the database, sma_costing table has the purchase_id column. When did you install the item?

Please try to run the query below after selecting your database

```
ALTER TABLE `sma_costing` ADD COLUMN `purchase_id` int NULL;
```

It should add the column.

Thank you

thank you Eng Now is working but i want to know if you made changes all other tables to avoid other errors

Hello,

**What other errors are you having?**

If you follow the install/update instructions the change will be applied.

Thank you
