 * The tables seem to have a size limitation. We have fairly large catalog files
   that sometimes will not save and I get errors while trying to save them. I tried
   the cron route and that did not work. I have tried the clearing cache route and
   that did not work either. Is there something we can try with the config file?

 * Hello,
 * wpDataTables itself doesn’t impose any hard limit on the number of rows or columns
   in a table. However, WordPress and your hosting environment may have limitations
   that can affect performance — especially when large datasets are loaded entirely
   in the HTML of the page, which can slow down or even crash the browser.
 * If you’re experiencing errors while saving, it’s possible you’re hitting a PHP
   timeout or memory limit on your hosting server. When the error occurs, please
   open your browser’s developer console (F12 in Chrome), switch to the **Network**
   tab, and look for any failed requests. In the **Preview** or **Response** section,
   you may find a more detailed error message.
   If it’s a timeout, you can check 
   your current limit in **wpDataTables → System Info**, then ask your hosting provider
   to increase the PHP execution time.
 * Some recommendations based on table size:
    - **2,000 – 5,000 rows**: Enable our [**Cache and** **Auto-update cache**](https://wpdatatables.com/documentation/table-features/caching-data-and-auto-update-cache-in-wordpress-tables)
      feature for better performance.
    - **5,000+ rows**: We strongly recommend switching to an **[imported table](https://wpdatatables.com/documentation/creating-new-wpdatatables-with-table-constructor/importing-data-to-editable-mysql-table-from-excel-or-csv-with-table-constructor)**,
      which supports **[server-side processing](https://wpdatatables.com/documentation/table-features/server-side-processing)**—
      only one page of data is loaded at a time via an AJAX call, significantly 
      reducing load stress. Please note, this feature is not available in the free/
      Lite version.
 * It’s also possible that a formatting issue in your source file (e.g., a spreadsheet)
   is triggering an error — we’d need to test the actual file to confirm.
 * If I recall correctly, you mentioned in a previous post that you’re using **Google
   Sheets** as your data source — that integration is part of the **premium** version
   of the plugin.
   In this case, please open a premium support ticket following this

   One of our agents will be happy to assist further.
 * As per WordPress.org guidelines, commercial products are not supported in these
