Can i please see a link where are you having this? I tested on my side, but there is no error showing.
If you can add some wp credentials in your profile, would be great. So i can check this and fix it in the same time.
Read this article for more information.
I fixed it.
In file includes/codeless_functions_portfolio.php i edited this line: $target = 'target="'.codeless_portfolio_item_permalink_target().'"';
To this: $target = 'target='.codeless_portfolio_item_permalink_target().'';
I removed only the double quotes. We will included the fix in the next theme update.
