Errors on saving table

    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 feature for better performance.
    • 5,000+ rows: We strongly recommend switching to an imported table, which supports 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.
