PHP Notices

Hello

I got a few PHP-notices in log. I use last Cobalt, Joomla! and PHP 7

05-Dec-2016 18:18:31 UTC] PHP Notice: Undefined variable: catid in /home/...../public_html/components/com_cobalt/views/record/tmpl/default_tags.php on line 53

[05-Dec-2016 18:12:05 UTC] PHP Notice: Undefined property: stdClass::$url in /home/...../public_html/components/com_cobalt/fields/html/html.php on line 146

[05-Dec-2016 18:45:06 UTC] PHP Notice: Undefined property: stdClass::$url in /home/........./public_html/components/com_cobalt/fields/html/html.php on line 146

I have no problems that i expect has some with this three notices to do.

Also, i dont use any parameter on "width" in imagefield, i let it be blank. That generates some notices in log. Is there any other value i can use to rezise width of image to the max avibilie space?
