Menus not displaying in the admin

We need to add a menu to the top Nav but when we click the menu link under appearance the screen is blank. I checked the log file and this is what I found

2018/06/18 15:01:42 [error] 15319#0: *603508 FastCGI sent in stderr: “PHP message: PHP Fatal error: Uncaught exception ‘InvalidArgumentException’ with message ‘The namespace for this manifest file has already been rex
Stack trace: x
#0 / EventEspresso\core\services\assets\Registry->registerManifestFile(‘event-espresso-…’, ‘https://x

On a separate site which is not live, I was getting the same issue so I deactivated event espresso and I was then able to login to the menu. If you would like access to this then let me know so you can view and test the problem as this is not a live site.

This seems to be a similar problem to mine – but there is no feedback on where we are with solving this issue.

Thanks in advance

Hi Andrea,

We added a fix for this to 4.9.63.

Please update to the latest version of EE (currently 4.9.63.p) and see if that prevents the error on your site.
