[Tikiwiki-users] Migrating Tiki9.7 to Tiki15.4 (LTS)

[Karsten Wemheuer]

Hi everyone,

after upgrading an old tiki (9.7) to the current LTS (15.4) I see a
label "Show php error messages" at the bottom of the pages. After
clicking on the label, I see following messages:

PHP (5.6.30-0+deb8u1) NOTICE (E_NOTICE):
File: modules/mod-func-search.php
Line: 146
Type: Undefined index: tiki_search
PHP (5.6.30-0+deb8u1) NOTICE (E_NOTICE):

Line: 177
Type: Undefined index: tiki_search
PHP (5.6.30-0+deb8u1) NOTICE (E_NOTICE):
File: modules/mod-func-search.php
Line: 192
Type: Undefined index: tiki_search

Where do they come from? 

Thanks,

Karsten
