Thank you for the quick response and the updated version!

Important clarification: I only have ONE shortcode on my site: [chatbot-2] which calls a single assistant. I don’t use multiple chatbots on the same page. The issue was that this single assistant shortcode wasn’t working at all (returning “error” with no response), while [chatbot] (general API) worked fine.

I tested the version you provided, but still encountered some issues that I had to fix:

1. Headers Already Sent Warning (line 58)
The setcookie() in kognetiks_assign_unique_id() still triggers a warning when headers are already sent. I added a headers_sent() check:

if (!headers_sent()) {
    setcookie(...);
}

2. Infinite Retry Loop on Failed Runs
When OpenAI returns status: failed, the code keeps creating new runs in an infinite loop until timeout. I added detection of failed status and automatic stop after a few consecutive failures.

3. Root Cause of My Original Issue
The assistant was failing because:

• max_prompt_tokens was set too low (2000) for my assistant instructions (~5000+ tokens)
• The model was returning server_error with very long instructions
• I had file_search enabled without a Vector Store attached

After shortening my instructions and moving content to a Vector Store file, everything works now.

4. Ukrainian Translation Files
I created translation files for my Ukrainian-Spanish site:

• uk.php
• chatbot-globals-uk.php

If you’re interested, I can send you the Ukrainian translation files for other Ukrainian users.

Best regards

Hi, Stephen and thank you.
Unfortunately, it didn't help.

When sending a message (e.g., “test”), the chatbot returns “error”.
I did as you recommended. I've cleared and disabled LiteSpeedCache plugin, cleared Cloudflare cache.
This is my system:
Chatbot Version: 2.4.0
PHP Version: 8.3.25
PHP Memory Limit: 1024M
WordPress Version: 6.9
API STATUS: Success: Connection to the OpenAI API was successful!
I haven't been monitoring the use of the plugin for several months, so I can't even say when exactly the problem appeared.

These logs may be helpful:
[Chatbot] [ERROR] [2025-12-20 17:24:23] [Session ID: N/A] [User ID: 1] [IP Address: xxxxxx] [Error:] []
[Chatbot] [ERROR] [2025-12-20 17:24:59] [Session ID: N/A] [User ID: 1] [IP Address: xxxxxx] [Error:] []
[2025-12-20 17:30:53] [Chatbot] [Advanced Reset] Cache and locks reset by admin user ID: 1 - Cleared 55 entries

Test email from the Chatbot Conversation Digest system (my message appears 2-3 times, even though I only sent it once):
[2025-12-20 19:14:20] Visitor: hi
[2025-12-20 19:17:09] Visitor: hi
[2025-12-20 19:17:11] Chatbot: The system is busy processing requests. Please try again later.
[2025-12-20 19:55:51] Visitor: test
[2025-12-20 19:58:53] Visitor: test
[2025-12-20 20:01:54] Visitor: test

I found out that the OpenAI platform logs contained the following inputs:
System: You are a test function for Chat.
User: Write a one sentence response to this test message.
Instead of my messages. And as I see it, these are some kind of test inputs for the chatbot, not my “hi” messages to the assistant. 

Thank you for your reply and for trying to help. The site uses Essential Addons for Elementor free version 5.9.21. From the beginning of my work on the customer’s site, the plugin was version 3.9.15, and then I updated to the latest version – 5.9.21.

There were also problems with the server, we transferred it to another VPS, tried different versions of php (up to 8.2), and settled on 7.4 because it was an outdated theme without the possibility of updates.

We also tried to test it with the twenty three theme. But there was a fatal error on the site, so I can’t say whether the button would work with it. We had to return to the current theme.

At the moment, the owner of the site has disabled the button on my recommendation. If it is possible, I will write back after the weekend when she is ready to enter the admin panel.
There are 3-4 java script errors in the console, but they relate to outdated cherry plugins, which are also duplicated in the theme. No notification about Essential Addons for Elementor until you click on the button.
Caching is now enabled on the site, but we tested without it, as I wrote earlier

I have disabled WP Rocket and cleared the browser page cache, if it is important to know. Also, in the HTML, the div tag with id=wfspb-main-content is empty (where the message should be). The developer tools console does not contain any errors related to this plugin. It is important for me to understand whether this situation can be fixed so that I know whether to recommend the client to buy the pro version
