* I have just upgraded to php 8.2 from 8.1 and my sites are going fine. However
they all get these errors – PHP Warning: Undefined array key “SERVER_NAME” in/
home/silkyfl1/zzzzz.com/wp-content/plugins/stopbadbots/stopbadbots.php on line
112
PHP Warning: Undefined array key “REQUEST_METHOD” in /home/silkyfl1/zzzzz.
com/wp-content/plugins/stopbadbots/stopbadbots.php on line 116
* Have never seen the error before the upgrade. Can you please advise, thanks

* Hi Tibbie,
* It’s not an error; it’s just a warning.
* Your hosting provider is blocking access to this PHP variables: $_SERVER[‘SERVER_NAME’]
* and
* $_SERVER[‘REQUEST_METHOD’]
* This is a legitimate operation; many plugins and themes will require it. It shouldn’t
be blocked.
* Please try contacting them to see if they can enable it.
* Then, please let me know.
* Cheers,
Bill

* Hi Tibbie,
* We are expanding on the previous answer by providing additional information and
insights.
* Your WordPress site should never display PHP warnings on the screen.
* **Why you should hide PHP warnings:**
- **They affect your site’s credibility:** Visitors may lose trust in your site
if they see warnings displayed.
- **They expose vulnerabilities:** Warnings can reveal potential security issues
to hackers and other malicious actors.

* I hope this is helpful.
* Cheers,
* Bill

* Bill, from the server people – After investigating this for you, we created a
test script that utilizes the variables mentioned by the plugin developer and
they work fine. We’d suggest contacting the developer again and informing them
of this.

* I never display errors, they came via email, S

* Hi Tibbie,
* Have you seen this only once or is the warning recurring?

* Hi Tibbie,
* Anyway, try the new version 9.22. I hope it works fine on your server.

* Bill, the recurring emails come through every 30 minutes, on the hour and half
hour. 30 minutes is the current server cron job setting.
* I am currently using Version 9.22 | By [Bill Minozzi](http://stopbadbots.com/)
* If you have no other thoughts I will simply extend the cron setting so does not
annoy, thanks S

* Tibbie, in version 9.22, I made a change. First, I checked if the variable exists(
should always exist).** Then, the line number is changed.** Please check the
line number for any warnings. Perhaps your server is delivering old emails. Also,
verify the date and time of the email.

* Bill,
* the date and time appear ok. As a matter of interest I added define(‘DISABLE_WP_CRON’,
true); onto line 86 in wp-config.php which should be pretty safe and now get
this message via currently dated email – any use?
* ```wp-block-code
