Getting a error message on the front end

product details page
Notice: Undefined index: pinterest_display in /home/content/....../html/plugins/system/hikashopsocial/hikashopsocial.php on line 195

and

when I use compare option

Notice: Array to string conversion in /home/content/...../html/libraries/joomla/filter/input.php on line 201

Anyone know what these error messages are?

Hello,
These are notice messages, Thanks for the feedback, Note that when you shop is in production mode you should :
- Disable the Joomla debug mode ("Administration->Global configuration->System->Debug System/Language")
- Set the "error reporting" option of the Joomla configuration to "none"

Thanks

hi , does this not indicate that there is some error ? I am also getting a similar error :

( ! ) Notice: Undefined index: print in /var/www/html/civil_air_new/templates/3rddesign35/component.php on line 26

is there anything we can do to fix this problem ?
