Error message every 15 min.

(@flicker177)

Hi Jacob,

On 4/10/2026 I started getting an error message every 15 minutes that references WPPA. I have my own cron system for WordPress that runs every 15 minutes. In my cron logs I notice the only thing referencing WPPA is a wppa-cleanup function that runs once an hour. Here’s a snippet of the error log:

Any idea what might be causing this? Thanks!

I looked at this a bunch more, its really strange. I doubt it’s WPPA’s fault. I tried de-activating all the plugins in the site except WPPA. That made no difference. I noticed that the error occurred every time my WordPress cron ran (cron job) but that nothing related to WPPA ran every 15 minutes.

The file referenced in the error message and line 56 don’t look like they have any relation to the error.

The cron job used curl to access the file wp-cron.php by https every 15 minutes. I found that if I used php to access the wp-cron.php file it ran fine and the error didn’t occur.

On a local staging machine running a setup pretty similar to my host, the cron job with curl runs fine and generates no errors. I don’t know what’s different from my host. Interestingly I can’t get the cron to work on that machine using php but the version using curl works fine. Maybe that’s a permission issue, I haven’t spent much time on it.

Anyway I hope this helps and I seem to be error free now.

Oooops…It seems my cron using php rather than curl does not work. So I’m back to the curl version and generating errors every 15 minutes. I’ll keep looking…

I do note that if I de-activate WPPA the error message goes away so I guess WPPA is actually involved but I don’t see how.
