Hello Steve

Thank you for your purchase.

For me, all three tables load fine, but it would be good if you can simply disable caching on pages where wpDataTables are. The plugin does face some issues with caching plugins, and the only solution at this point is preventing caching for pages where our tables are.

Hi again Steve

Thank you for your feedback!

We're aware of the issue, and the whole plugin is scheduled to have the code refactored at some point in the future, where avoiding the usage of AJAX is also on the table. Our team is working their best to develop the plugin, fix existing bugs and troubleshoot ongoing issues, so a venture this vast has been put on hold for some time now.

Once we get to it, I'm sure our developers will find a better way to handle server-side tables. You don't see this issue with tables linked to an existing data source (CSV, Excel, Google Spreadsheets, etc) because these tables fetch all the rows, output the entire table to the front-end all at once, and then split it into pages using JavaScript; all data processing (page switching, sorting, filtering) is done on the client’s computer by JavaScript, so no admin-ajax is being called.

Every suggestion and ticket like this is forwarded to our developers, so they have an overview of the situation. I'll send them this ticket as well, hoping that the AJAX function will be avoided in the future.

Thank you once again for your help!

Hi again Steve.

Our developers confirmed that we are planning to enhance the back-end of the plugin in the future. For now, we have a workaround for working with Litespeed Cache:

We do not use wp_create_nonce, but wp_nonce_field, but anyway you can forward the action in their hook.

You need to go to file ..wp-content/plugins/wpdatatables/templates/frontend/table_main.inc.php and around line 21, you will find this:

<?php wp_nonce_field('wdtFrontendEditTableNonce' . $this->getWpId(), 'wdtNonceFrontendEdit_' . $this->getWpId()); ?>

Above that, add this:

<?php do_action( 'litespeed_nonce', 'wdtFrontendEditTableNonce' . $this->getWpId() ); ?>

If you're using Excel-like tables, then you also need to go to file ..wp-content/plugins/wpdatatables/templates/frontend/excel_table_main.inc.php and around line 20 you'll find this:

<?php wp_nonce_field('wdtFrontendEditTableNonce' . $this->getWpId(), 'wdtNonceFrontendEdit_' . $this->getWpId()); ?>

Above that line, add this:

<?php do_action( 'litespeed_nonce', 'wdtFrontendEditTableNonce' . $this->getWpId() ); ?>

That's how it's supposed to be done based on their instructions.

Please let me know if this works, and we'll add the hook to wpDataTables.
