Hello,

Please check the server requirements in the documentation.pdf specially MySQL `only_full_group_by` mode.

Lastly check the server error logs and let me know the error details so that I can suggest solution.

Thank you

thanks for your reply .i do not think it is only_full_group_by mode because every other function works perfectly

i looked into the request and response data i have a screen shot attached.

as you can see from the attachment i think it is a code bug in the software

Hello,

You need to check your server error logs to know the 500 error details. It might be cause to various reasons and without the error details I can't suggest.

You can enable app logs by changing the `log_threshold` to 1 in `app/config/config.php` and the perform the action again to produce errors. Lastly check the latest log in the `app/logs/` folder.

Thank you

You can check https://stackoverflow.com/questions/23921117/disable-only-full-group-by and with your server admin/host. Thank you

I have the same problem, and I have ONLY_FULL_GROUP_BY disabled.
I don't know what to do, I have no way to add the products

Please ask new question with details and screenshot. SMA disables mode on session level. The might be due to some other reason. You can check your server php error logs and add the details to your question.

Thank you
