Can someone tell me what’s going wrong? 🙁 Viewing 13 replies - 1 through 13 (of 13 total) * [Mark (podz)](https://wordpress.org/support/users/podz/) * (@podz) * [20 years, 8 months ago](https://wordpress.org/support/topic/comment-page-database-errors/#post-238326) * When did this start, and what did you change just before it happened ? * Thread Starter [bk](https://wordpress.org/support/users/bk/) * (@bk) * [20 years, 8 months ago](https://wordpress.org/support/topic/comment-page-database-errors/#post-238327) * I just added the default gravatar in the comment preview yesterday. After that, I didn’t test if the comments were working (How stupid of me!). Just right now, a friend of mine posted a comment and he told me that it’s displaying an error. * The problem could be in the default gravatar that I added in the comment preview. * Thread Starter [bk](https://wordpress.org/support/users/bk/) * (@bk) * [20 years, 8 months ago](https://wordpress.org/support/topic/comment-page-database-errors/#post-238330) * I just removed that default gravatar from the comment preview. The problem still exists. Do you think I should create a new/repair MySQL Database? * I am also getting errors when I try to delete a comment. * Thread Starter [bk](https://wordpress.org/support/users/bk/) * (@bk) * [20 years, 8 months ago](https://wordpress.org/support/topic/comment-page-database-errors/#post-238333) * And I also installed PluginsUsedPlugin and RunPHP Plugin. * Thread Starter [bk](https://wordpress.org/support/users/bk/) * (@bk) * [20 years, 8 months ago](https://wordpress.org/support/topic/comment-page-database-errors/#post-238347) * Can someone please help?! * [Mark (podz)](https://wordpress.org/support/users/podz/) * (@podz) * [20 years, 8 months ago](https://wordpress.org/support/topic/comment-page-database-errors/#post-238348) * Have you UNinstalled everything you put in ?? * Thread Starter [bk](https://wordpress.org/support/users/bk/) * (@bk) * [20 years, 8 months ago](https://wordpress.org/support/topic/comment-page-database-errors/#post-238350) * Yes, podz, I have.
