PHP Code error on Page

Dear All,

I have experienced the PHP code error when upgrading my Joomla from version 3.6 to 3.9 (the recent one).

The PHP error is

" Notice: Undefined property: stdClass::$rating in F:\xampp\htdocs\limsawad\templates\jux_graphsign_business\html\com_content\category\blog_item.php on line 70 "

on my blog category page.

my website: www.limsawad.com

I have no knowledge about PHP at all but I know it is just minor problem (my site don't crash). I will try to study PHP but right now I would like your help to correct the code for me.

And if possible, please let me know what you have done. so i would know if the similar problem occur, I might be able to correct it myself.

Thank you

Sorry HaiND,

Last night, I tried to find the way to correct the error by myself and couldn't find one so I just revert my joomla version back to 3.8.12 which has no error.

I just forgot to come back here and delete the thread becuase I worked on it until very late night.

However, I did come up with the new problem.

I just created the new row (with addon "Latest article" on SP Pagebuilder) on my homepage called "WANT YOU TO KNOW". It should work just like your "LATEST BLOGS" part on your demo site.

The latest article has no result even though there is one article I just created.

I checked the code it seems that the module has not been generated. This is out of my reach so I need your help.

Thank you.

Hello HaiND,

I have sent you email about my login yesterday.

Please check and solve the problem for me.

Thank you
