Hello Ilia

Did you add any auto-refresh intervals in the tables? That's the only reason why it would be doing that.

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. 

Make sure to tell me on which pages does this happen, and which tables are located on those pages.

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

Hi again Ilya

You can't even add that to your tables, since they are all Google Spreadsheet based tables. Auto-refresh is only available on manual and SQL query based tables.

I took a look at these pages, though, and I couldn't see the issue where they are reloaded at all. They load once, and they stay like that:

I can't find any other pages where wpDataTables are shown on front-end, and if you're still facing this issue, please provide me URLs to those pages, so I can take a look.

You're welcome, Ilya

No need to do anything, this will be fixed with the next update.

Hello Toinette

Please go to wp-content/plugins/wpdatatables/controllers/wdt_functions.php and delete this line:

set_site_transient('update_plugins', null);

From line 861.

Then delete cache from your website and browser, and you should have no issues.
