Hi,

I have a cron job with the following command:
/usr/bin/php /home/user/public_html/folder/file.php
When it runs, I get this warning:
PHP Warning: Trying to access array offset on null in /home/user/public_html/wp-content/advanced-cache.php on line 869

The mentioned line of code appears to be:
$excluded_urls = $swcfpc_config['cf_fallback_cache_excluded_urls'];

My settings are:
Cache Engine: Enabled
Background Tasks: Running
Cloudflare Caching: Inactive

I’m using version 5.1.4. Thank you.

Hi there,

Thanks for reporting this. The warning you’re seeing:
```
PHP Warning: Trying to access array offset on null
```
usually happens when something is trying to read an array value that doesn’t exist or is null. We’re not able to reproduce this on our side, so we’ll need a bit more detail to investigate:
- The full error message (from your PHP error log).
- Your WordPress and PHP versions.
With this information we can check if it’s coming directly from the plugin or being triggered by something else in your setup.

Best regards,

Hi,

Thanks for your answer. The message I shared is already the full error message. There is nothing else.
WordPress version is 6.8.2. PHP version is 8.3.

Hi @kushnamdev
I have additional information to share. The PHP file includes:

do_action(“swcfpc_purge_cache”, array(
“https://example.com/url1”,
“https://example.com/url2”,
“https://example.com/url3”
));

The error occurs when this action is executed. It is probably not related to the fact that it is called by a cron job, so my previous assumption was wrong. It is caused by this code. Thank you.

It appears this thread is connected to this as you have confirmed as well, so I am closing this one and marking as resolved – https://wordpress.org/support/topic/question-how-to-purge-cache-programmatically-from-php-using-swcfpc_purge_cache/
