Question

Hi everybody

I get this error in the error.log. how it can be resolved?

one of the plugins that are related to this error is warnonleave 

PHP message: PHP Question2Answer more info: Methods with the same name as their class will not be constructors in a future version of PHP; qa_layer_14_from_q2apro_warnonleave_layer_php has a deprecated constructor in eval()'d code from .../qa-plugin/q2apro-warn-on-leave-master/q2apro-warnonleave-layer.php" while reading response header from upstream, client: **.**.**.**, server: www.bidbarg.com, request: "GET /bimeh/46318/%D9%85%D9%82%D8%B1%D8%B1%DB%8C-%D8%A8%DB%8C%D9%85%D9%87-%D8%A8%DB%8C%DA%A9%D8%A7%D8%B1%DB%8C 

Answer 1

It looks like that was solved a while back. The last change to the plugin from 11 months removes the old style constructor. I just checked on my PHP 7.1 test install, and it works fine.

Does this work for any q2a version?

If you are using PHP7, replace function name of class constructor from "class name" to "__construct".

Thanks for your answer,

I'm little familiar with PHP. How the "__construct"  should be added to the following line?

    class qa_html_theme_layer extends qa_html_theme_base {
