SMF 2.0.15 Search redirects to main page

[CMBurns]

Hi,

I'm working on migrating an existing forum to a new environment (Linux -> Win16). Until now everything seems to work quite well after I made a clean install from scratch and imported most of the existing db tables.

I skipped the import of all search related tables as they seemed to be too large. Instead of using the existing ones I decided to build a new full text index.

Now I face the challenge that with every search I try I'm redirected to the main page, no matter which option I activate (no index, full text index).

Start point: index.php?action=search; index.php?action=search;advanced;search=
End point: index.php?action=search2 -> start page

Any idea what's wrong there?

PHP: 7.1.19
MySQL: 8.0

Any hint is appreciated.

Well, you imported "most" db tables.

What tables did you skip exactly?
Do you get any errors in either SMF or server error log when that happens?
