Direct Invoice Ajax Post response cancelled after 10 seconds on large bills

[M-Shahbaz]

Dear FrontAccounting,
Thank you very much for this wonderful software.
I already opened ticket: http://mantis.frontaccounting.com/view.php?id=3376

Currently we are facing issue when placing a direct invoice with large number of product items on FrontAccounting 2.3.24.

I enabled the debug option with 2 in config file but the error is not displaying just an exclamation indicator.

Apparently direct invoice generates successfully despite the error but page does not updates.

We have 500+ products listings and database size 30MB+.

I attached the screenshot when I was placing direct invoice with more than 40 products.

I configured php with set_time_limit(500) but error still occurs.

I look forward for your support at your earliest convenience.

Regards,
M Shahbaz

I set (max_input_vars) in php.ini in start of using this software to 10,000.

This issue can be reproduced manually if:

sleep(10);

put first line in sales/sales_order_entry.php
