script errors getting logged

Hi there.

This works great, but seems to be turning up errors in the log that look like this:

bla=false, referer: http://maps.glin.net/cmsdev/category/mapgallery/

Commenting out these lines seems to fix the issue:

error_log("bla=".print_r(WPCTC_Settings::get_instance()->settings['general']['do-not-load-scripts'], true));

error_log("bla=".(!isset(WPCTC_Settings::get_instance()->settings['general']) ? "true" : "false"));

error_log("bla=".(!isset(WPCTC_Settings::get_instance()->settings['general']['do-not-load-scripts']) ? "true" : "false"));

error_log("bla=".(WPCTC_Settings::get_instance()->settings['general']['do-not-load-scripts'] != 1 ? "true" : "false"));
