* See below the extracts of the debug log for the plugin: seems to be misfiring:
* ```wp-block-code
[15-Jun-2026 00:48:14 UTC] WordPress database error You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'FROM wp_ipr_avif_conversions' at line 2 for query SELECT PERCENTILE_CONT(0.9) WITHIN GROUP (ORDER BY original_size) FROM wp_ipr_avif_conversions made by shutdown_action_hook, do_action('shutdown'), WP_Hook->do_action, WP_Hook->apply_filters, IPR_AVIF_Queue->process_if_due, IPR_AVIF_Queue->process, IPR_AVIF_Queue->estimate_ram_batch[15-Jun-2026 00:48:16 UTC] PHP Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the disable-dashboard-for-woocommerce domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress

* Hi Melvin,
* Good news on the log line you pasted earlier: it’s fixed. The RAM batch estimator
was running a PERCENTILE_CONT query that MySQL 8 and MariaDB don’t support in
that form, so it threw a syntax error into your debug log on every queue run.
A fallback was already handling the actual calculation, so conversions were never
affected — it was log noise, not a functional bug. I’ve replaced it with a portable
percentile calculation, released just now in v1.9.8. Once you update, that error
will stop appearing.
* While I was at it I also corrected the declared “Requires PHP” to 8.1 to match
the codebase.
* On the second item: as a rule I don’t open files hosted on external/temporary
file-sharing links from support threads — nothing personal, it’s just a security
practice I keep to. If there’s anything else in your log you’d like me to look
at, the best way is to paste the relevant lines directly here as text and I’ll
dig into them right away. The PHP notice about the “disable-dashboard-for-woocommerce”
text domain, for what it’s worth, comes from that other plugin and isn’t related
to this one.
* Thanks again — update to 1.9.8 and let me know if anything still shows up in
the log.

* Excellent thank you. Fixed
* About external file, I use that to demonstrate the bug, without saving the image
on my server as this is for demonstration purposes and these files automatically
expire later on , on a temp domain. Maybe you could recommend your preferencial
temp site. It is worth nothing at wordpress.org does not allow image uploads
here, so it tricky.

* Glad it’s fixed! And thanks for explaining — that makes sense, and you’re right
that wordpress.org doesn’t allow image uploads in the forum, so I understand
the need for an external link.
* For sharing screenshots, my honest recommendation is to skip the temporary file-
hosts — some of them wrap the download page in aggressive ads/redirects that
can land on sketchy pages, which is the only reason I didn’t open the earlier
ones (nothing personal, just a habit I keep). A couple of cleaner options:
- Imgur (imgur.com) or a GitHub Gist for images — direct, no redirects, free.
- For logs specifically, the easiest is to just paste the relevant lines as
plain text right here in the reply. Text is actually better than a screenshot
for me anyway, because I can copy the exact query or error string and search
the codebase for it directly.
* So for anything log-related, plain text in the thread is ideal. For visual stuff(
UI glitches etc.), an Imgur link works great.
* Thanks again for all the testing — genuinely made the plugin better this week.

* Great and thanks for you recommendation. Will register at imgur.
* Sure I will paste code errors here if any issues arise
* I am grateful for all the timely fixes. Cheers
