extra innovation

I solved that issue, but now I cannot post any comments. wp-comment-post.php is blank. The last update of wordpress and accesspress lite brought many changes, so now my child theme is not compatible. I don’t want to lose a lot of time to apply changes to every single file I’ve modified. Do you think I should upload an older version of wordpress?

Thank you, but my problem is not the notice, but how to solve that issue. Suddenly all my posts stopped displaying because of this undefined index.

Hi, I’ve customized it myself, thanks!

Hi, thank you for your answer! Yes, I’ve already done that, but I want every new article that I publish to be posted automatically as a welcome post on top of the page.
