BigScoots found that there was some leftover data in the database from an old plugin that was causing some issues. The plugin name was Link Whisper Free. They fixed the issue and things are back to working again! Thank you for all your help 🙂 * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Yoast Duplicate Post] Critical Error Message and Duplicating Posts](https://wordpress.org/support/topic/critical-error-message-and-duplicating-posts/) * Thread Starter [thomask0702](https://wordpress.org/support/users/thomask0702/) * (@thomask0702) * [1 week, 3 days ago](https://wordpress.org/support/topic/critical-error-message-and-duplicating-posts/#post-18893040) * I wish I could say it worked, but I’m still getting the same message. I had done a fresh reinstall prior to contacting you the first time, but never cleared the OPcache so I tried that this time and I’m still getting that same error message. Do you think I should put a support ticket into Bigscoots and see if they can figure out why it’s not working? * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Yoast Duplicate Post] Critical Error Message and Duplicating Posts](https://wordpress.org/support/topic/critical-error-message-and-duplicating-posts/) * Thread Starter [thomask0702](https://wordpress.org/support/users/thomask0702/) * (@thomask0702) * [1 week, 3 days ago](https://wordpress.org/support/topic/critical-error-message-and-duplicating-posts/#post-18892182) * Hi, thanks for getting back with me so fast! * I’m clicking on rewrite & republish. I’ve used it many times over the past couple of years and I love it and it usually works great for me. * I don’t trust myself not to mess something up by adding that to my wp-config file, so I’ve copied the error part of the email I got. It took them a while to finally send me the email.
