Hi Eduardo,
Thank you for your purchase.

1. 
With wpDataTables built-in functionalities it is not possible to apply sorting on column that is not visible.

But I can give you some workaround. 
For that column that you want to be sorted select ascending or descending. 

For that column that you want to be hidden DO NOT uncheck visible checkbox because sorting will not be applied in the table.

To hide that column and to have sorting in same time you will have to add this little script on your page where the table is located.

<script>
jQuery( window ).load(function() {
wpDataTables.table_1.api().columns(0).visible(false)
});
</script>

Where number 0 is the first column in the table, 1 is second, 2 is third...  Just change it with the number of the column you want to hide.

2.
For URL column types please take a look at our documentation where you can find some useful hints how to make URL columns.

3. 
Sorry but i did not understand what are you trying to tell me, can you please describe me more. Thank you.


NOTTICE:

When I go to your page I see an error

TypeError: wpDataTables[b.tableId].rowGrouping is not a function

This error was in 1.7 version of our plugin and today 1.7.2 version is released. Auto update is not ready yet but if you wanted to upgrade it manually you can follow these steps:

1.) Download zip from this link

2.) Use FTP to open /yourwordpressfolder/wp-content/plugins

3.) Delete existing wpdatatables folder.

4.) Upload previously downloaded wpdatatables folder through FTP to plugins folder (unzip it)

5.)  Go to WP-admin panel, open Plugins section.

6.) Deactivate wpDataTables, and then activate it again.

Hi Eduardo,

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.

Hi Eduardo

"When I try to modify a table it is left thinking without executing anything."

Can you please try now and tell me do you still have that issue.


About hidden column
Can you please try to change the theme and see if it will work, i just tased on few tables and it is working.

Hi Eduardo,


Nice to hear that now everything is working fine.

About hidden column:

I just realised that you are using server side table and unfortunately this script will not work and it will require some code customization.( it is working on non server side tables so you can check it)
So for now it is not able to hide the sorting column on server side tables.

But we can recommend this service for customizations: https://wpkraken.io/?tms-plugins (by this link they would know you come from us) - they do develop such custom solutions, could you please send your inquiry to them? They have a promo hourly rate of $29/hour currently. So maybe they can implement this functionality for you.
Thank you for understanding.
