In dedeCms background module management, the module list is not displayed, as shown in the following figure:

Solution:

If you have a backup website program, find the following folder in the backup program as follows:

The code is as follows:	Copy code
Data/module

Copy all the files and paste them to the same folder in the program to overwrite all the files.

PS: If there is no backup website, go to the dedecms official website to download a source program with the same version as yours, overwrite the file according to the above method, and then update the cache.

The following figure shows the blank management of the dedeCms background module:

Solution:

This is because you have installed the module and then uninstalled the module. You have chosen to delete the installation file when uninstalling the module. This problem occurs. Download a DEDE program of the same version as your website, and find include/dedemodule. class. php: If you upload this file to the directory of your website, you will not be prompted to overwrite it. It is estimated that the file is deleted together, which is a BUG.
Everything is OK. Module management is no longer blank
