Hi Pete,
Thank you for your purchase.

I was able to create a table with your spreadsheet. ( attachment) 

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.

Best regards.

Hi Peter

The issue probably because that curl expected the certificate to be at the path /etc/ssl/certs/ but could not find it because it is on different path or does not exist.

My suggestion is to contact your hosting provider to tell you where this certificate is located on server.

Best regards.

Hi Peter

The SSL certificate is necessary for connection with https , it can be overwritten with few line of codes. 

In local host it should be working because SSL is not included there.

Best regards.

Hi Peter,

Can you please tell me which OS are you running.

Best regards.

Hi Peter,

Can you please check now.

I added this line of code 

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

in file ../wp-content/plugins/wpdatatables/source/class.wdttools.php around line 145 

You will be able to see that code.
Also please tell me does the Spreadsheet upload is working for you because I tested it and it is working.

Best regards.

Hi Peter,

Can you please check now and tell me do you see the wpdatatables support table that I created on your site.

Also tell me do you still see that PHP warnings.

Best regards.

Hi Peter,

First in file
../wp-content/plugins/wpdatatables/templates/admin/table-settings/add_column_modal.inc.php i found this line of code

<?php foreach ($tableData->table->columns as $column) { ?>    <option value="<?php echo $column->orig_header; ?>"><?php echo $column->display_header; ?></option>
<?php } ?>

and I added some changes to look like this

<?php if (is_object($tableData)){
foreach ($tableData->table->columns as $column) { ?>
<option value="<?php echo $column->orig_header; ?>"><?php echo $column--->display_header; ?></option>
<?php }} ?>

Then in file 
../wp-content/plugins/wpdatatables/templates/admin/table-settings/remove_column_modal.inc.php I found this line of code

<?php foreach ($tableData->table->columns as $column) { ?>   
 <?php if ($column->orig_header == 'wdt_ID') {        continue;    } ?>    <option value="<?php echo $column->orig_header; ?>"><?php echo $column->display_header; ?></option>
<?php } ?>

and change it to look like this

<?php if (is_object($tableData)){
foreach ($tableData->table->columns as $column) { ?>
<?php if ($column--->orig_header == 'wdt_ID') {
continue;
} ?>
<option value="<?php echo $column->orig_header; ?>"><?php echo $column--->display_header; ?></option>
<?php }} ?>

I just added IF condition in both of those files which gave you a warnings. ( attachments)

Hope this can help you out.

Best regards.

Hi Peter,

Glad that we solved the issue.

I forwarded this to my team and I hope that it will be included in the upcoming release.

Just made a backup of that files and if the changes are lost you can follow the guide that I gave you below, but like I said I will emphasize to add this fix for the next version.
Unfortunately I can not tell you precisely the date of the release but we are working on it.

You are welcome.

We'd greatly appreciate it if you could take a minute and leave a review on CodeCanyon on this link. Thanks!
