Solution to UPLOAD FILETYPE NOT ALLOW error when uploading images in dedeCMS_PHP Tutorial

Recently, I installed the official dedecms version 5.7 program. When publishing an article, I discovered a problem. When uploading pictures through the editor during the publishing process, the pictures could not be uploaded and an error message was given. It's: "Upload filetype not allow...". After careful research, the author finally came up with a solution. I'd like to share it with you here.

It’s actually very simple. Find the file /include/uploadsafe.inc.php and make the following modifications on line 45 of the file:

$imtypes = array

changed to

$imgtypes = array

After the above modifications are completed, update the whole site cache and the problem will be solved.
