Title: Call to undefined function wp_get_upload_dir() Last modified: December 4, 2016 --- # Call to undefined function wp_get_upload_dir() * Resolved [Carlos_FRS](https://wordpress.org/support/users/carlosfrs/) * (@carlosfrs) * [9 years, 5 months ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_upload_dir/) * Updated last night to version 4.6 from 4.5.1 and had white screens across all my multisites. WP Debug logs showed thousands of \nFatal error: Call to undefined function wp_get_upload_dir() in /wp-content/plugins/contact-form-7/includes/functions. php on line 18. `$uploads = wp_get_upload_dir();’ Checked line 18 on version 4.5.1 and saw different code. `$uploads = wp_upload_dir();` Reverted back to 4.5.1 for the time being and works fine. Probably could have changed the line in version 4.6 but didn’t have time.

Maybe something is off on my end. Thank you and thank you for such a great plugin. I will post back what I find. * Thread Starter [Carlos_FRS](https://wordpress.org/support/users/carlosfrs/) * (@carlosfrs) * [9 years, 5 months ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_upload_dir/#post-8519854) * Thank you again for your help. You were correct we found a few sub 4.6 servers. Issue has been resolved. * [malcstewart](https://wordpress.org/support/users/malcstewart/) * (@malcstewart) * [9 years, 4 months ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_upload_dir/#post-8652110) * Hi, * Just to add to this discussion, we have 2 mirrored installations of a site on 2 different 1and1 hosting accounts (Europe). One of them works fine with CF7 version 4.6 but the other throws the same error as outlined above. * Both sites are on WP version 4.6.2. * We tried both the rollback to 4.5.1 and editing line 18 of includes/functions. php in the 4.6 version of the CF7 plugin’ **from** wp_get_upload_dir() **to** wp_upload_dir(). Both these options worked, so I don’t know what it is between our 2 different 1and1 accounts, but thought I would share this info for anyone having problems. * [malcstewart](https://wordpress.org/support/users/malcstewart/) * (@malcstewart) * [9 years, 4 months ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_upload_dir/#post-8652140) * UPDATE to note above: I updated the non-working version to WordPress 4.7.1, and reinstated the wp_get_upload_dir() and it’s working. * I can only imagine some problem occurred with the cloning of the site from one server to the other. * Great plugin – thanks * M * [jacobross85](https://wordpress.org/support/users/jacobross85/) * (@jacobross85) * [9 years, 3 months ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_upload_dir/#post-8783632) * Changing wp_get_upload_dir() to wp_upload_dir() worked for me on WordPress 4.7.2. There must be an action that doesn’t call the wp_get_upload_dir() yet. Seems to be a common issue as well. * [rubyannrsls](https://wordpress.org/support/users/rubyannrsls/) * (@rubyannrsls) * [8 years, 11 months ago](https://wordpress.org/support/topic/call-to-undefined-function-wp_get_upload_dir/#post-9247090) * Changing wp_get_upload_dir() to wp_upload_dir() worked for me too on WordPress 4.4.5. Thanks for the information. This is a goldmine!
