 * I have recently moved over from the CodeCanyon plugin to the new Vanquish Premium
   version with a lifetime license. However, when I activate the plugin, it breaks
   the product pages it is associated with. When I troubleshoot and deactivate the
   Vanquish plugin, all is well, but I need my customers to be able to upload files
   for their purchase. I have been struggling with this since Friday 10th, and I
   really need to fix it when we open on Monday 13th July.
   WordPress version 7.0.1Active
   theme: Storefront (version 4.6.2)Current plugin: Vanquish Upload Files for WooCommerce
   Premium (version 1.0.12)PHP version 8.3.32

 * Hi,
   Thanks for reaching out, and sorry for the trouble — I understand the timing
   is tight with your Monday opening, so let’s get this sorted quickly.
 * The good news: since the pages work again as soon as you deactivate the plugin,
   this is almost certainly a single, identifiable error (a PHP conflict or a fatal
   on the product page). A debug log will usually let me pinpoint it straight away.
 * **Could you enable logging and send me what it records?** Here’s how:
    1. Edit your site’s `wp-config.php` file (in the WordPress root folder). Just above
       the line that says `/* That's all, stop editing! Happy publishing. */`, add 
       these three lines:`define( 'WP_DEBUG', true );define( 'WP_DEBUG_LOG', true );
       define( 'WP_DEBUG_DISPLAY', false );`(`WP_DEBUG_DISPLAY` is set to `false` on
       purpose, so your visitors won’t see any error messages while the shop is live.)
    2. With the Vanquish plugin **active**, open one of the product pages that breaks.
       This makes WordPress record the error.
    3. Open the file `wp-content/debug.log` and copy me its contents (or just the last
       section, from the moment you loaded the page).
 * If the debug log shows nothing related to the plugin, the issue may be in the
   browser instead. In that case, please also open the broken product page, press**
   F12** to open the browser console, and copy me any errors shown in red under 
   the “Console” tab.
 * You can reply here or — if it’s easier to attach the log file — open a ticket
   here and attach it directly: [https://vanquishplugins.com/support/](https://vanquishplugins.com/support/)
 * Once you’ve turned debugging on and captured the log, feel free to set those 
   three lines back to `false` (or remove them).

 * Hi,
   Please try updating the plugin to the latest 10.0.13. I was working for a
   fix for another user and **maybe** that fix works also for your case.Please give
   it a try and let me know, Thank you!
