The comment could not be saved. No comment_ID on comments

I had the same problem and it was indeed solved by turning on Auto_Increment (A_I) for “comment_ID”. Here’s how to do that: https://stackoverflow.com/questions/5665571/auto-increment-in-phpmyadmin

In my case, “comment_ID” was not set as a Primary Key and I received an error (1075). It was easily fixed by assigning a Primary Key to “comment_ID”. See this: https://stackoverflow.com/questions/19198397/mysql-how-to-set-the-primary-key-on-phpmyadmin
