Tell us what you are trying to do?
Updated my plugins, however when I do, it causes a failure (attached image).
Is there any documentation that you are following?
No
Is there a similar example that we can see?
No
What is the link to your site?
hidden link
This is a strange error - where does it happen?
In the Plugins list, or Commercial Installer, or Dashboard > Updates section?
Can you head to wp-admin/admin.php?page=otgs-installer-support and send me a screenshot of that?
If you need the update immediately, you can always grab it manually from https://toolset.com/account/downloads/ and follow the manual update steps https://toolset.com/faq/how-to-install-and-register-toolset/
But if you have the time, I would like to analyse it and if possible adjust/fix so you can simply use the Update button.
I also suggest enabling WP Debug and letting me know if any error happens during the update.
https://codex.wordpress.org/WP_DEBUG
I get the failure message inside the plugin window.
Can you try to do the steps recommended and feedback with the results?
My issue is resolved now. Thank you!
