Greetings, The file name is a partial misnomer. Warnings and errors go into this file.
[Thu Oct 29 13:41:00 2015] opac-search.pl: C4::Context->userenv not defined! at /usr/share/koha/lib/C4/Items.pm line 1355. [Thu Oct 29 13:53:31 2015] opac-detail.pl: C4::Context->userenv not defined! at /usr/share/koha/lib/C4/Items.pm line 1355., referer: https://www.google.com.tr/ I searched these errors but I didn't found about it. What does these means? How can I solve these errors?
These two messages are WARNINGS. If you had opac logins enabled, and you logged in, you would find that these messages would not be triggered. Yes, these will fill the logs, but that is the real problem to solve, not the messages themselves. Also, you didn't state what version of Koha you are using, because it is likely line 1363 in master.
