FrixelOne: Undefined variable: pageTitle in header.php

[Didier9]

I get this error in the log:

Undefined variable: pageTitle in /var/www/html/getsimple/theme/FrixelOne/header.php on line 61

I just installed 3.3.8 but it was the same with 3.3.4

Here is line 61:

<!--<li <?php if ($pageTitle=="Main Template") echo 'class="active"'; ?> ><a href="index.php">Main Template</a></li>

$pageTitle does not seem defined anywhere in that module, but maybe it is supposed to come from somewhere else?

Not sure what to do to fix it...

Thanks in advance

Didier
