[Closed] Activating Plugin Triggers Fatal Error

Hi there.

Before this ticket gets assigned to one of my colleagues, I will try to help.

That is a general error message and we can't know what is causing the error until we don't dig a bit deeper.

Let us share the steps that you can use to find out more about what is the actual error when you see a general error message like that one.

We can enable the WordPress debug log and recreate the issue to see if we are getting a longer error message that is more specific.

This will allow us to see if any PHP errors are being produced.

In order to do that, we can edit the wp-config.php file inside our WordPress directory and insert the following lines:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

Now, we can try to reproduce the issue once again.

We should now be able to locate the debug log in: /wp-content/debug.log

Paste the content (if any) on a site like pastebin.com and then share the link with us (only you and us will see the URL you are sharing, it is automatically hidden for anyone else).

Please let us know how things go.

Hello,

Welcome to the WPML support forum.

It appears that a file is missing from the plugin, as indicated by this error message:

[26-Sep-2024 14:36:46 UTC]No such file or directory in /wp-content/plugins/sitepress-multilingual-cms/inc/lang-data.php on line 10

Could you please try manually re-uploading the plugin? You can easily download our plugins from your WPML account:

- Go to https://wpml.org/account/downloads/
- Click on "Download WPML manually" to see all plugins and download the core plugin WPML CMS
- In your WP dashboard, go to "Plugins > Add new" and use the button at the top of your screen to upload the .zip file

Alternatively, you can upload the plugin via FTP. Here is an online tutorial: hidden link

Hello,

Perhaps the file is corrupted or it could be a permission issue.

1. I would still recommend to reupload the plugin.

2. Make sure that the files have a permission 644 and your folders 755.

Hello,

Could you please provide me with a temporary admin access and FTP access.

I've activated a private field for your next answer where you can provide that information safely (this field is only visible by you and the support team). Don't share your own admin account, create a new one that you will delete when we finish troubleshooting.

IMPORTANT: Before we proceed, please backup your site and database.

Hello,

As I mentioned you can get a fresh copy of WPML CMS directly from your WPML account.
- Go to https://wpml.org/account/downloads/
- Click on "Download WPML manually" to see all plugins and download WPML CMS
- Re-upload all the files to your server via FTP
