Too many warning events

[mariano1405]

Hi everyone, i'm getting too many of these warning in the log events, causing the event table grows fast.

E_NOTICE Undefined index: platform_view - in /var/www/html/testlink/gui/templates_c/428f65c814945c41498633fb818023333b2a5eaf.file.mainPageLeft.tpl.php - Line 205

TL version is 1.9.18 [Dev] (Gaura)

Any ideas of what could be causing the events?
Thanks.
