Hello Roberto

We've had an issue with this in version 3.4 but it was fixed with v3.4.1.

If the table tools are turned off, there's no edit button.

Please update the plugin to v3.4.1, clear cache from your website and browser and test again.

Let me know if that works.

Hello again Roberto

You should not roll back to a previous version of the plugin, since this issue should not even exist, and previous versions of the plugin are not supported.

You also can't do it from the Plugins section, because wpDataTables doesn't exist in WordPress' repository, so the version you see there is the Lite version of the plugin, not the full version.

Please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. 

You can write credentials here just check Private Reply so nobody can see them except us.

Thank you Roberto

I forwarded the issue to one of our developers, and as soon as he responds, I will let you know.

Hi again Roberto.

All these tables seem to be Gravity Forms based tables.

However, you don't have our add-on for Gravity Forms installed, you only have core Gravity Forms and some other plugin.

You need to install Gravity Forms Integration for wpDataTables add-on, and it should work fine after that

I'm glad to hear that, Roberto

Thanks for letting me know.

If you have any further questions or issues, please feel free to open a new ticket, and we'll gladly help.
