Unknown E_NOTICE error

Have just upgraded to REVO 2.2.2 and am now getting this error multiple times on every page load:

[2012-05-17 10:21:09] (ERROR @ /index.php) [OnWebPagePrerender]

<b>Notice</b>: Undefined index: browser in <b>/var/www/html/core/cache/includes/elements/modplugin/6.include.cache.php</b> on line <b>201</b>

<b>Notice</b>: Undefined index: browser in <b>/var/www/html/core/cache/includes/elements/modplugin/6.include.cache.php</b> on line <b>131</b>

No other errors, and no idea what's causing it. Any clues?

What is the plugin with the ID of 6 (in parentheses next to the plugin name in the Elements tree)?

You can disable the plugin by editing it and checking the "disabled" checkbox and saving it.

You can also fix the code of the plugin to eliminate the warning. It's telling you that that line in the plugin is referencing an array index called 'browser' that doesn't exist.

That got rid of the error. The Plugin was the MobileDetection package. Should I make a notification to the developers of the issue?

Yes, the fix is probably very easy and the problem may affect a number of people.

BTW, here is a fix, not necessarily the right fix, but I think it may stop the messages:


Around line 125 of the plugin, change this code:



to this:
