Hi, Mary 

Thanks for reaching  out to us

Yes, the user from that ticket corresponded with my colleague in a separate, private ticket, and the solution was shared with them at the time.

On their site they had a specific conflict between wpDataTables and another plugin's CSS styles, that plugin was overriding our default styles, thus preventing the column settings from properly showing on back-end.

This user had a conflict with this plugin Document Viewer for Office.

This plugin loads their CSS on all pages, so the user had to add the following code to functions.php of their theme, or the child theme:

function wdtRemoveEmbedScript (){
 if (isset($_GET['page']) && (strpos($_GET['page'], 'wpdatatables') !== false))
 wp_dequeue_style( 'eov-admin-css');
}
add_action('wpdatatables_enqueue_on_admin_pages','wdtRemoveEmbedScript');

In case if you have the same conflict with this plugin, then this should solve it,

but it is possible that you have a different issue/conflict with something else on your site.

-

I will provide instructions, if the above does not solve it, here is how you can test for conflicts.

Can you please change the theme and see if the issue is resolved?

 If not, then please deactivate all other plugins except for our plugin, refresh the page where the issue is, and see if it is resolved (it should be). 

If it is, then start activating other plugins one by one, and after each activation refresh the page to see if the issue occurred. 

Once it does reoccur, you will have found the plugin causing the issue.

Let me know how it goes, and if you "catch" the conflict. Thank you

Hi, Mary 

Sorry for the delay

-

1.  In regards to not being able to see column settings:

The other user from the ticket you referred to had a conflict on site with another plugin.

It is standard procedure when we test for a conflict on any site,

the user has followed our instructions and they isolated that they have a conflict between our plugin and another plugin on site.

-

You would have to try to change your WP Theme first,  then refresh the page and see if the issue goes away.

If it does, this means that there is a conflict between our default plugin styles and some style or Bootstrap of your Theme is overriding it.

-

If that does not help, and it is not an issue with the Theme;

then you would have to disable all plugins and just leave wpDataTables enabled - refresh the page again, see if you can then see the column settings.

If that is the case - then you can enable other plugins one by one, 

and after each one refresh the page again,

when the issue appears - then you will find which plugin  ( or Theme)  is causing the conflict.

-

There is no other way to test for conflicts,

so if you do not wish to try these steps, the only other way is if you wish to make a Testing/Staging version of your site , and then do these steps there,

that way you don't have to change anything on your live site but you can do the testing on the Staging site.

-

If you do not wish to do any of that , and need us to do all the troubleshooting for you -

we will still need either a Staging version of the site, or duplicated copy.

Would you be able to provide us with a staging site, along with WP-admin (Administrator) user, FTP, and the database, so our developers can debug the plugin, and see what's going on?

If you're not able to provide us with a staging site, can you clone your website?

If yes - I'll ask you to install the Duplicator plugin. It will generate a couple of files that you can send me (along with the log-in credentials), and then I can create an exact copy of your website, see what the issue is and try to resolve it.

The Duplicator plugin can export only up to 500MB of data, so if your site is bigger than that, please use the All-in-One WP Migration plugin.

Please note that the files will be too large to attach to the ticket, so you can upload them via wetransfer.com and just send me the link.

And make sure to mark reply as PRIVATE, so that only we can see the credentials and your data.

2. In regards to the background of just the wrench icon to the right of the column header is white, while the column header background is gray when it's in focus;

I am sorry, but i did not understand what the issue is.

I am guessing that you would like to see a different behaviour/colors?

Can you tell me what is the desired color/behaviour,

and which table skin are you using?

It looks to me that it is the "Light table skin" from the Customize, but not sure.

For example, that is how the default style is for "Light skin",  the table that we sort by on default has this "gray background" with the white background on the "cog",  but we can change that with CSS,

and here is how the Aqua table skin looks :

if you could just clarify the goal and we can work on some basic CSS for you.

I will also need the URL of the page where this table is, and access to the back-end if you'd like us to change the colors for you,

Please provide me a temporary WP-admin (administrator) user 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 parties. 

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

and provide me with this table ID.  Thank you

Hi, Mary 

Firstly, I would like to sincerely apologize for the delayed response as we have been experiencing an unusually high number of tickets. I am sorry that it has taken longer than usual to respond to your concern and your patience is highly appreciated.

-

Thank you for this update,

i can see that the conflict with PDF Poster was the issue.

If that plugin is not crucial for you - or if you can find an alternative for it,

in that case you can simply keep it disabled;

-

Or if it crucial to have that on the same site with our plugin,  our developers can try to work on debugging the conflict,  

but we can't guarantee success - we can certainly do our best.

If that is the case, let us know if it is a free plugin, then we can download it and try to reproduce the issue on our end;

or if it is a premium version of the plugin, then you could send us the plugin files and we can work on isolating the issue.

-  And of course, if you send us anything like that, make sure to mark reply as PRIVATE - so that only we can see it.

Thank you
