Hi, 

After update on php 7.1 when I try to use jomla site search  I have following error:

 0 Using $this when not in object context 

I saw in the log log that the problem is Search - GPS Tools plugin:

[28-Oct-2018 11:16:56 UTC] PHP Deprecated:  Non-static method JoomlaCMSApplicationSiteApplication::getMenu() should not be called statically in /home/.../plugins/search/gpstools/gpstools.php on line 134

If I disable Search - GPS Tools plugin everything works fine.

How can i solve this?
