Title: Error when creating new menu Last modified: July 1, 2021 --- # Error when creating new menu * Resolved [studioavanti](https://wordpress.org/support/users/studioavanti/) * (@studioavanti) * [4 years, 11 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/) * Hi, * I’ve noticed that Nav Menu Collapse prevents to create new menus on my site: an error is thrown in frontend every time i try to, no details in the notification. Disabling the plugin solves the problem. * It might be related to a plugins conflicts on my install, i didn’t dig more further nor checked the server’s log, will do if i have the time.

I will do some testing and see if I can pinpoint the issue on my side as well. * Thank you, Robert * Thread Starter [studioavanti](https://wordpress.org/support/users/studioavanti/) * (@studioavanti) * [4 years, 11 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14620415) * Hi [@rnoakes3rd](https://wordpress.org/support/users/rnoakes3rd/), * Thanks for your answer. * It doesn’t seem to be a plugins conflict, i disabled all but Nav Menu Collapse and still get the red error notification in Admin > Appearance > Menus when creating a new menu * Maybe it’s rather related to the server config: PHP 7.4 / nginx / fastCGI Or some custom PHP in this site, i have to investigate. * Moreover, it’s the first time i get this error when using your plugin which usually runs fine. So, probably an issue specificly related to this site. * Plugin Author [Robert Noakes](https://wordpress.org/support/users/rnoakes3rd/) * (@rnoakes3rd) * [4 years, 11 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14620434) * Thank you again, [@studioavanti](https://wordpress.org/support/users/studioavanti/). Please keep me posted during your digging. * Thread Starter [studioavanti](https://wordpress.org/support/users/studioavanti/) * (@studioavanti) * [4 years, 11 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14620522) * [@rnoakes3rd](https://wordpress.org/support/users/rnoakes3rd/) A new clue: the error doesn’t occur with the “Store Collapsed States” option disabled. * Plugin Author [Robert Noakes](https://wordpress.org/support/users/rnoakes3rd/) * (@rnoakes3rd) * [4 years, 11 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14620595) * [@studioavanti](https://wordpress.org/support/users/studioavanti/), * While enabled, the plugin taps into the window.wpNavMenu.eventOnClickMenuSave function and makes an AJAX call to save the stored states before saving the menu. I just tested this functionality on a few sites with no issues. Is there anything in the error log that could shed some light on this? Perhaps AJAX is failing somehow? * Thank you for digging, Robert * Thread Starter [studioavanti](https://wordpress.org/support/users/studioavanti/) * (@studioavanti) * [4 years, 11 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14623332) * Hi [@rnoakes3rd](https://wordpress.org/support/users/rnoakes3rd/), * You’re right, it looks like an Ajax error, but hard to tell. * The browser console return a 400 error with this file: [https://site.com/wp-admin/load-scripts.php?c=0&load%5Bchunk_0%5D=jquery-core,jquery-migrate,utils&ver=5.7.2:formatted](https://site.com/wp-admin/load-scripts.php?c=0&load%5Bchunk_0%5D=jquery-core,jquery-migrate,utils&ver=5.7.2:formatted) * ``` POST https://site.com/wp-admin/admin-ajax.php 400 send @ load-scripts.php?c=0&load[chunk_0]=jquery-core,jquery-migrate,utils&ver=5.7.2:formatted:3918 ajax @ load-scripts.php?c=0&load[chunk_0]=jquery-core,jquery-migrate,utils&ver=5.7.2:formatted:3680 s.ajax.s.ajax @ load-scripts.php?c=0&load[chunk_0]=jquery-core,jquery-migrate,utils&ver=5.7.2:formatted:4363 S. @ load-scripts.php?c=0&load[chunk_0]=jquery-core,jquery-migrate,utils&ver=5.7.2:formatted:3795 eventOnClickMenuSave @ script-36f434cb33.js?ver=2.1.0:2 (anonymous) @ nav-menu.min.js?ver=5.7.2:2 dispatch @ load-scripts.php?c=0&load[chunk_0]=jquery-core,jquery-migrate,utils&ver=5.7.2:formatted:2030 v.handle @ load-scripts.php?c=0&load[chunk_0]=jquery-core,jquery-migrate,utils&ver=5.7.2:formatted:1962 ``` * Plugin Author [Robert Noakes](https://wordpress.org/support/users/rnoakes3rd/) * (@rnoakes3rd) * [4 years, 11 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14624844) * [@studioavanti](https://wordpress.org/support/users/studioavanti/), * Being a 400 error, there could be something in the PHP error log. Do you have access to that? If not, is there any way you could turn on site debugging (WP_DEBUG) so I could get more accurate line numbers for the errors in the console? * Thank you, Robert * Plugin Author [Robert Noakes](https://wordpress.org/support/users/rnoakes3rd/) * (@rnoakes3rd) * [4 years, 10 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14686950) * [@studioavanti](https://wordpress.org/support/users/studioavanti/), * I just released a new version of the plugin that contains some changes to the assets. This may or may not resolve your issue. If it does not, would you mind sending a copy of the theme my way so I can do some testing on my side? * If I don’t hear from you within a week, I’m going to close this ticket out. * Thank you, Robert * Thread Starter [studioavanti](https://wordpress.org/support/users/studioavanti/) * (@studioavanti) * [4 years, 10 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14686970) * Hi [@rnoakes3rd](https://wordpress.org/support/users/rnoakes3rd/), * Thanks for the update, sorry i didn’t had the time to troubleshoot my issue any further, moreover, it’s beyond my scope. * Ok, i’ll test with the new version of the plugin and report. * Thread Starter [studioavanti](https://wordpress.org/support/users/studioavanti/) * (@studioavanti) * [4 years, 10 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14688674) * Hi, * Just tested Nav Menus Collapse latest version 2.1.1, it doesn’t fix my issue unfortunately. * When the “Store Collapsed States” option is enabled in the plugin’s General Settings, i can’t create a new menu, an error message is displayed in a red box at right bottom of the screen. * The issue disappears once the option above is disabled. * Probably an Ajax conflict as mentioned previously, outside of my scope, not a blocking problem either, i don’t create menus every 5 minutes. 😉 * Plugin Author [Robert Noakes](https://wordpress.org/support/users/rnoakes3rd/) * (@rnoakes3rd) * [4 years, 10 months ago](https://wordpress.org/support/topic/error-when-creating-new-menu/#post-14689924) * Thank you, [@studioavanti](https://wordpress.org/support/users/studioavanti/)! I’m going to close out this ticket for now. If anyone else has a similar issues, please let me know.
