Title: Fatal Error Message Last modified: August 31, 2016 --- # Fatal Error Message * [willbrogan](https://wordpress.org/support/users/willbrogan/) * (@willbrogan) * [10 years ago](https://wordpress.org/support/topic/fatal-error-message-seeking-help/) * Website: [http://www.commercialtrucktraining.com](http://www.commercialtrucktraining.com) Theme: OnePress Plus Notable Plugins: WishList Member, POWr (various) * I attempted the 4.5.1 update twice yesterday but it never finished, to my knowledge. Maybe it now has. * I am not in control of hosting, FTP, etc. at this time. * Error I receive: Fatal error: Cannot redeclare is_comments_popup() (previously declared in /homepages/23/d97057843/htdocs/commercialtrucktraining/wp-includes/ query.php:309) in /homepages/23/d97057843/htdocs/commercialtrucktraining/wp-includes/ deprecated.php on line 3713 * Someone please help. We did a complete theme overhaul yesterday and were promoting the new look and functionality on social media, etc., and now I obviously cannot get in. Thank you!

Unfortunately FTP or file manager would be the only way to sort – I doubt it could be done without this. * Hopefully that would add any missing files and get you back up and running. * Thread Starter [willbrogan](https://wordpress.org/support/users/willbrogan/) * (@willbrogan) * [10 years ago](https://wordpress.org/support/topic/fatal-error-message-seeking-help/#post-7356877) * Phil, thanks for getting back to me. Can you tell me what ANY of that error message means? I assume a web developer/server operator would understand that, correct? * [girlieworks](https://wordpress.org/support/users/girlieworks/) * (@girlieworks) * [10 years ago](https://wordpress.org/support/topic/fatal-error-message-seeking-help/#post-7356882) * [@willbrogan](https://wordpress.org/support/users/willbrogan/): What the error message _means_ is that a function with the same name exists in two different files (which is not allowed in PHP). * And the _reason_ why two different functions with the same name exist in this case is that the `/wp-includes/query.php` file which currently exists on your server is from an older version of WordPress (4.4.2 or lower), but the `wp-includes/ deprecated.php` file is from the newer version of WordPress (4.5 or higher). * In other words, based on the error message, the update did _not_ finish properly, as it indicates that the files on your server are a mixture from two different versions of WordPress (instead of all being from the same version). * Thread Starter [willbrogan](https://wordpress.org/support/users/willbrogan/) * (@willbrogan) * [10 years ago](https://wordpress.org/support/topic/fatal-error-message-seeking-help/#post-7356884) * That’s a huge help to understand this on my level, thank you!! * [florentdevauchel](https://wordpress.org/support/users/florentdevauchel/) * (@florentdevauchel) * [10 years ago](https://wordpress.org/support/topic/fatal-error-message-seeking-help/#post-7356886) * [@girlieworks](https://wordpress.org/support/users/girlieworks/) Have you got a answer to finish the update or to access of the wordpress board? * [@willbrogan](https://wordpress.org/support/users/willbrogan/) Have you succeed to opening your website? * I have the same problem with the same error * Sorry for my approximative english 🙁 * [girlieworks](https://wordpress.org/support/users/girlieworks/) * (@girlieworks) * [10 years ago](https://wordpress.org/support/topic/fatal-error-message-seeking-help/#post-7356887) * [@florentdevauchel](https://wordpress.org/support/users/florentdevauchel/): The answer is in **Phil**‘s post above. * [@willbrogan](https://wordpress.org/support/users/willbrogan/): You’re welcome! * Thread Starter [willbrogan](https://wordpress.org/support/users/willbrogan/) * (@willbrogan) * [10 years ago](https://wordpress.org/support/topic/fatal-error-message-seeking-help/#post-7356888) * No success yet. My main problem lies in the fact that the web admin that set it up is no longer a part of the company (he’s actually the President’s nephew), but he still has the creds to the FTP, Server, host, etc. It was never a big deal until this happened. * I get everything said here on a conceptual level, and if it was on a server/host that I’m used to (I use GoDaddy for everything else), I could do it. But until I have access, I’m totally stuck! * Thanks all for your help everyone, it really has helped me grasp this and will( eventually) help me get it fixed.
