Resolved Why doesn't the search work?

Hi,
can you copy/upload from QS only this folder
templates\shaper_aspasia\html\mod_search

Use FTP tool

It seems that the problem is not in the folder
templates\shaper_aspasia\html\mod_search

I installed template only and it's OK, PHP 7.3

Do you have this same setting?

PHP 7.2.8

It looks this same, indeed.
Can you send me access to back-end?

No, I'm Sorry.
But I am ready to collect any information for you.

On a working site, you can't see the cause of the problem?
http://www.prompribor.ru/

I can show you a screenshot from my demo where it works.

I can ask someone for dev team for a clue.
---
I guess, you cannot send me website backup as well?
I don't need images folder.

1 GB backup

I need only Joomla basic files.
No images, no attachments.
This copy should be ~~100MB max.

I prepared the package. Where can I send it for you?

click to my avatar, then use Private Message button

I sent a message for you.

Can we hope for success?

Sorry, I had not planned delay.
I will check today deeper.

I will be very grateful for your help.

Ok, found. Sorry for the delay.

1) download topsearch.zip
2) unzip
3) Upload here (replace file)
templates\shaper_aspasia\html\mod_search

4) Check settings

I'm sorry, but..
Your topsearch.php is absolutely identical to our topsearch.php on the server.
Nothing has changed. http://www.prompribor.ru

On my copy of your site is OK now, maybe I forgot about something. No file.
Let check again.

If it wasn't searching module file, nor module settings
Probably it was/is JavaScript conflict.

Please for your own test disable code used for stats
HotLog, Yandex.Metrika,Bitrix24
AND
Affix bootstrap

then test search again

Disable JavaScript code, but it doesn't work.
How can I get your copy of my site?

Hi! Can we hope for success?

I can send you my working copy if you want.
Wait for a link

Sorry, but this is not the copy of my site that I gave you. Similar to Quickstart in many ways.
Let's go back to solving the problem.

You didn't return me a copy of my site, but a Quickstart version. I know that the Quickstart version doesn't have a search problem. Let's go back to solving the problem.

Hi! Can we hope for success?

In Quickstart -- there are only basic extensions and ours, none of them are causing JavaScript conflicts.
I think it would be better for you to use extra installed search module found on Joomla Extension Directory.
Or instead popup search use - link to search page from component, which always works.
