If that resolves the issue, reactivate each one individually until you find the cause. * If that does not resolve the issue, access your server via [FTP or SFTP](http://codex.wordpress.org/FTP_Clients), navigate to `/wp-content/themes/` and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule- out a theme-specific issue (theme functions can interfere like plugins). * Thread Starter [icdt3n-aDmN](https://wordpress.org/support/users/icdt3n-admn/) * (@icdt3n-admn) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170475) * Unfortunately, I am unable to find the original folder for my site. The site was created by someone who no longer works with us and it’s unclear as to where all of the files went that were on her computer. It must be somewhere though right? I originally thought that anyone who worked on the site would end up with a wordpress folder on their computer, but that doesn’t appear to be the case. Also, I’ve attempted to use Filezilla to access the server, but haven’t been having much luck. I might not be doing it correctly, but I’d like to think that I am. Anyways, as of right now, I’m at a loss. Any suggestions? Or perhaps know of an easier way to access the server? * [Lee](https://wordpress.org/support/users/romanempiredesign/) * (@romanempiredesign) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170477) * Nope, if you don’t have server access, you’re not getting into the server short of breaking in. * You will need to call your hosting company or server admin and get access so you can download all of your files. * However, to your original post, disabling your gravity forms plugin should do the trick. * Thread Starter [icdt3n-aDmN](https://wordpress.org/support/users/icdt3n-admn/) * (@icdt3n-admn) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170478) * It’d be an easy fix if I could just log into the site or find the original WordPress folder. Unfortunately, it is not my lucky day. * [Lee](https://wordpress.org/support/users/romanempiredesign/) * (@romanempiredesign) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170479) * Do you have FTP access? * Thread Starter [icdt3n-aDmN](https://wordpress.org/support/users/icdt3n-admn/) * (@icdt3n-admn) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170480) * I’ve tried using Filezilla and can establish a connection, but it lasts for a very short period of time, so I’m not able to do a whole lot. I’ve also found out that you can type [http://ftp.godaddy.com](http://ftp.godaddy.com) into the search bar and put in a username and password, not sure if that will help at all. That is the hosting site that we use. I’ll need to find out the username and password for our godaddy account if there’s a chance that it could work though because the username and password we have for the wordpress site don’t work for [http://ftp.godaddy.com](http://ftp.godaddy.com). * [RossMitchell](https://wordpress.org/support/users/rossmitchell/) * (@rossmitchell) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170482) * Filezilla is very helpful, it will reconnect upon demand. Just click and navigate as you need, Filezilla will look after getting the file lists, transfer data, etc. * Thread Starter [icdt3n-aDmN](https://wordpress.org/support/users/icdt3n-admn/) * (@icdt3n-admn) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170483) * Does it matter which username and password I use when using Filezilla? I’ve been using the one that I would use to log in to the wordpress site. And where it says host, what should I be putting in there? I know some people put in the IP address, but the one I have hasn’t been giving me much luck, so I was using ftp:// mysite.com and that was slightly working. The username works, but the password isn’t being accepted. I tried my own login information and again the username is accepted, but not the password, so I’m confused. Do I need to figure out the username and password for godaddy and use those in Filezilla? * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170485) * > Does it matter which username and password I use when using Filezilla?

You get your FTP connection details from your hosting provider. * Thread Starter [icdt3n-aDmN](https://wordpress.org/support/users/icdt3n-admn/) * (@icdt3n-admn) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170487) * Ok, thank you. As you can probably tell, I’m not overly familiar with FTP, so I really appreciate your help. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170488) * You’re welcome! 🙂 Viewing 11 replies - 1 through 11 (of 11 total) The topic ‘Fatal Error Message: Call to Undefined Function’ is closed to new replies. * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 11 replies * 4 participants * Last reply from: [James Huff](https://wordpress.org/support/users/macmanx/) * Last activity: [11 years, 10 months ago](https://wordpress.org/support/topic/fatal-error-message-call-to-undefined-function-1/#post-5170488) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
