UM 2.0 Installation crashes WP Admin – Appearance – Menus

Dear @ultimatemember

When i manually installed Ultimate Member 2.0 as described in your site, all functionalities work well. But if i try to enter to menu customization page from Admin Panel (WP Admin – Appearance – Menus), system crashes with Error-500. If i deactivate the UM-20 plugin and try again, problem disappears. If i re-activate UM-20 and try to go to menu customization page, problem appears again.

There were no such a problem in previous version UM 1.3.8.

This is only a bug-decleration that may help you before auto-deplayment.

Best Wishes
Mustafa
