The files change as you please.

I almost gave up web panel today.

I uploaded the downloaded zip file to install the plug-in.
https://www.wpxpo.com/

Activate, output error message.
Fatal error: Uncaught Error: Class 'ULTP_PRO\License' not found in /home/mainjo/public_html/wp-content/plugins/ultimate-post-pro/classes/Initialization.php:22 Stack trace: #0 /home/mainjo/public_html/wp-content/plugins/ultimate-post-pro/classes/Initialization.php(9): ULTP_PRO\ULTP_PRO_Initialization->requires() #1 /home/mainjo/public_html/wp-content/plugins/ultimate-post-pro/ultimate-post-pro.php(37): ULTP_PRO\ULTP_PRO_Initialization->__construct() #2 /home/mainjo/public_html/wp-admin/includes/plugin.php(2299): include('/home/mainjo/pu...') #3 /home/mainjo/public_html/wp-admin/plugins.php(191): plugin_sandbox_scrape() #4 {main} thrown in /home/mainjo/public_html/wp-content/plugins/ultimate-post-pro/classes/Initialization.php on line 22

First of all, I asked the production company to determine the cause.

The cause is missing a whole file.

I tested it again and found that one license file had zero bytes… …

Of course, if you upload that file additionally, it will be activated without any problems.ten thousand

Because I don’t have a personality like that… Besides, it’s a self-built server.

​

I also tested other plug-ins.

This time, the file was completely unzipped and unzipped.

The Classic Editor plug-in.

This is the original file.

This is the zip file that was unpacked after it was uploaded.

A random word will be added to line 906.

​

Trying to activate it in this state, of course not.

First of all, the web panel manufacturer informed us that it is not possible to apply.

​

The error log is uploaded only when it is activated (no log is generated during upload).

It doesn’t seem meaningful. The files have already been changed.
