Tell us what you are trying to do?
I'm tying to update 4 WMPL plugins:

WPML Media
WPML Multilingual CMS
WPML String Translation
WPML Translation Management

But they all give an error like:

An error occurred while updating WPML Media: The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature
Is there any documentation that you are following?

An error occurred while updating WPML String Translation: Download failed. Not Found

Is there a similar example that we can see?

What is the link to your site?

Hey Patrick,

Sorry for this issue. Can you go to the Dashboard area and select Updates from the left sidebar, please? Here, just hit the Check Again button and try again to update the plugins. Please let me know how things work this time.

Hello Radu,

Hitting the "Check Again" button has no effect. I still can't update the plugins.

Hey Patrick,

Please try these steps too:

  • go to Dashboard → Updates;
  • press the Check Again button;
  • press the Update button at the bottom of the page;
  • go to Plugins → Add New → Commercial;
  • press the Check for updates button;
  • go to https://wpml.org/account/sites/ look for your current key and erase it;
  • create a new one for your site;
  • go to Plugins → Add New → Commercial;
  • click on the Unregister WPML from this site button;
  • register WPML adding your new key;
  • try also disabling the Keep wpml.org up-to-date about which theme and plugins I use option.

If that does not fix the issue you can manually update the plugins.
❌ Before proceeding please make a full website backup! ❌

  • download the latest version of WPML from https://wpml.org/account/downloads/;
  • disable WPML Multilingual CMS
  • delete WPML Multilingual CMS (the settings and the translations are saved in the database so they will not be deleted);
  • upload the freshly downloaded WPML plugin from Plugins → Add New → Upload Plugin
    → Activate WPML
    ;

Please let me know if this solves the issue or if you need further details.
