I have 2 issues that need help with please.

1. AJAX doesn’t seem to be working. I put in the portfolio row CSS ID #projects and put that in the ID box of the plugin. Or I’ve tried to put the class .portfolio-wrap.
   Both way doesn’t work. Now, when I click on the filter, I need to refresh the page for the project to show, so AJAX is not working properly here. Kindly advise.
2. I need a reset button to clear each filter. How can I achieve this please?

Thank you in advance for your support.

1. Everything is up to date (CC 2.6.1, WSPG 9.3.1, WooCommerce 9.7.1, WP 6.7.2). All caching and minifying plugins have been switched off.
   
2. After selecting a product in my WC store, going through cart and ending in the checkout, the list of the seleced items appears there for a second, then (only) the section with the items and payment methods reloads and keeps forever loading/gets stuck.
   
3. When I disable Content Control, the checkout works fine again (items appear, then reload, all appear again).

Not sure what the cause is, possibly an AJAX issue, just reporting.

Issue:

Visitors click the submit button, but the form does not process their entries. No errors appear in console logs, server logs, or Gravity Forms logs. Form submissions succeed when manually entering details, but fail when autofilled via URL parameters (e.g., [email protected]&fname=John). Happens on fresh WordPress installations with only Gravity Forms and a page builder installed. What I’ve Tried:

• Disabled caching (Cloudflare, WP Rocket)
• Disabled security features (ModSecurity, firewalls, security plugins)
• Switched hosting (Hetzner → Hostinger → SiteGround)
• Tried multiple form plugins (Gravity Forms, Fluent Forms, WPForms, Ninja Forms)
• Used a fresh WordPress install on a subdomain, but the issue persists
• Tested with and without ad blockers – no difference
• Checked Hotjar recordings – visitors click submit, but the form hangs
• Plugin support (Gravity Forms, Elementor) couldn’t replicate the issue.

Additional Notes:

• Plugin support (Gravity Forms, Elementor) couldn’t replicate the issue.
• No PHP errors are logged.
• Hotjar recordings show users clicking submit, but the form does nothing.
• This issue existed before Hotjar was installed, so it’s not a conflict.
• Debug logs don’t show blocked requests.
• The issue seems to happen universally regardless of form, page builder plugins, or themes

Additional Clues:

Issue occurs before submission is processed (even with simple confirmation messages instead of redirects). Form submissions don’t even register as clicks in Hotjar for Elementor and Formidable forms. The issue happens for almost all real visitors, not just specific ones. No 403/404 errors in server logs, but POST requests from real users don’t seem to reach the server.

How visitors access the form:

1. I send an email with a Pretty Link (Prettylink1).
2. Prettylink1 redirects to another Pretty Link (Prettylink2).
3. Prettylink2 redirects to the final form URL.
4. Visitors land on the form page but fail to submit unless manually interacting with fields.
5. Even when testing direct visits (bypassing Pretty Links), the issue still happens

Possible Causes? JavaScript not executing properly for real visitors? AJAX requests getting blocked silently? ModSecurity filtering requests without logging errors? I’m out of ideas at this point—has anyone encountered anything similar or have suggestions for further debugging?

and here: https://www.ads-software.com/support/topic/ajax-search-stops-working-due-to-caching/#post-18346826

The people at Ivory Search suggested: “Please contact the WP Super Cache plugin support below to know how to exclude is_ajax_nonce from the cache.”

Is this possible?

To be clear, I don’t want to exclude posts/pages from caching that use this ajax search, as I have the search bar set to appear in the sidebar of every post/page.

Thanks

I see this topic here, with a solution related to ESI: https://www.ads-software.com/support/topic/ivory-search-stops-returning-results-after-a-few-days-of-cache-being-active/

But I don’t see an option for this within WP Supercache. Is Ivory Search incompatible with WP Supercache, or is there another solution I can use to fix this issue?

Better still is that it supports custom post types right out of the box which many plugins don’t without having to put some form of workaround in place. I have a large(ish) archive of posts from an old site that I can never really figure out how to share effectively and this plugin solves that problem for me.

• Publishing or editing posts
• Editing with Elementor
• Liking posts
• Other admin-related actions

This issue started immediately after running the following code:

session_destroy();
clear_wordpress_cache();
wp_cache_flush();
$wpdb->query("DELETE FROM $wpdb->options WHERE option_name LIKE ('_transient_%')");
$wpdb->query("DELETE FROM $wpdb->options WHERE option_name LIKE ('_site_transient_%')");
flush_rewrite_rules();
clear_wordpress_cache();

Some actions return the following error response:

{
  "code": "rest_cookie_invalid_nonce",
  "message": "Cookie check failed",
  "data": { "status": 403 }
}

What I’ve Tried So Far:

Checked Browser & Cleared Cookies
Disabled Security Plugins (Wordfence, iThemes Security, etc.)
Regenerated .htaccess by visiting Settings → Permalinks → Save Changes
Verified File Permissions (755 for folders, 644 for files)
Checked if Cloudflare, ModSecurity, or Firewall is blocking requestsPossible Causes?

• Deleting _transient_% and _site_transient_% entries from wp_options may have removed security-related tokens used by WordPress and plugins.
• session_destroy(); might have cleared active session data, causing authentication failures.
• REST API nonces became invalid, leading to rest_cookie_invalid_nonce errors.

Questions:

1. How can I restore the correct transient data if it’s causing these issues?
2. Could this be related to missing security tokens or authentication issues?
3. Any recommended steps to debug the persistent 403 error?

Any insights or solutions would be greatly appreciated!
Thanks in advance for your help.

This version clearly outlines the problem, lists debugging attempts, and asks specific questions, making it more effective for getting help. Would you like me to adjust anything further?

{code: “rest_cookie_invalid_nonce”, message: “Cookie check failed”, data: {status: 403}}
code
:
“rest_cookie_invalid_nonce”

this is a multisite, we have couple of cache pluggin installed but active in respective projects only. i have nitropack ut deactivated it. Kindly help me with the solution.
