The reason for the error should be visible in the error log. You can find it in your hosting area. If necessary, the support of your hosting can help you.

Alternatively, you could also enable debugging in WordPress. How to do this is described here: https://developer.ww.wp.xz.cn/advanced-administration/debug/debug-wordpress/ – also here the support of your hosting can help you if necessary to edit the file accordingly.

In both cases you should be able to see what the cause is in the logfile.

If you view your observation as a recommendation for optimizing the WordPress Core, I would suggest opening a ticket for it in Core Trac.

However, I took a look at the specific lines you mentioned and noticed that you do not appear to be running the latest version of WordPress. For instance, in the current version, line 1469 of wp-includes/media.php contains no PHP code that would trigger the warning message you described: https://github.com/WordPress/WordPress/blob/master/wp-includes/media.php#L1469

It is possible that this specific issue was resolved in WordPress 7.0 thanks to a ticket in Core Trac; see: https://core.trac.ww.wp.xz.cn/ticket/60480

Consequently, the other error messages you encountered may also be obsolete. However, there is currently an open bug ticket regarding this issue for height and width specifically in relation to SVG graphics: https://core.trac.ww.wp.xz.cn/ticket/57239

My recommendation, therefore, is as follows:

• Update your WordPress installation to version 7.0 and check whether the warning messages persist.
• If they do, deactivate all plugins to rule them out as the cause. You should also switch to a default theme, such as Twenty Twenty-Five. Users are strongly advised to take this step to ensure that the problem is not caused by a plugin.
• If the issue continues to occur – even with no plugins active, using a default theme, and running the latest WordPress 7.0 – please feel free to open a ticket in the WordPress Core Trac. When doing so, please describe the exact steps required to reproduce the error (including, if possible, the specific image file that triggered the issue for you): https://core.trac.ww.wp.xz.cn/newticket – only under these conditions will developers have the opportunity to identify and implement potential improvements to the Core.

Thanks for the details. I took a look at it on my end and can’t find any problem with the shortcode in the editor.

I tested this in a fresh WordPress 7.0 installation, using only the plugin you mentioned and the HTML block you mentioned along with its content. The exact same process works without any issues in the Playground as well (except that the Playground won’t load the images on the front end, but that’s likely a Playground-specific issue).

I would therefore recommend first checking whether any other plugins might be interfering here. Try deactivating all of them except for the Gallery plugin whose shortcode you’re using.

Another tip would be: you’re getting a message saying the code is incorrect. Take a look at the surrounding code in the editor – the error might actually be caused by something completely different. To test this, you could simply create a new page and enter only the shortcode there, with nothing else.

And there’s one more thing I’d recommend. You’re using a shortcode. So I’d also suggest inserting it via the Shortcode block rather than the HTML block. See: https://ww.wp.xz.cn/documentation/article/shortcode-block/

This is usually a secondary error caused by a plugin you’re using incorrectly calling WordPress core functions. To rule this out as the cause, try deactivating all plugins. If the error message no longer appears, reactivate the plugins one by one until you find the one causing the problem.

Yes, it’s likely a server-side error. It might be because a plugin you’re using isn’t compatible with changes in WordPress 7.0. I’d therefore recommend taking another look at the error log to find the cause and, ultimately, a solution.

Alternatively, you can try deactivating all plugins and change the theme to a default theme like TwentyTwentyFive and see if that changes the behavior.

Unfortunately, I can’t seem to reproduce the issue you described at all. My guess is that a plugin you’re using is causing the problem. Try deactivating all plugins to see if that makes a difference.

By the way, I also see a known bug on your end (probably the lesser problem for you right now). The links next to the update button are misaligned. You can find the ticket for this here: https://core.trac.ww.wp.xz.cn/ticket/65286

The theme Underscore is neither being developed further nor supported anywhere. See its repository: https://github.com/automattic/_s

It’s therefore quite difficult to understand your question. You can’t just download the theme and see your customizations there. We might be able to help if you provide a link to your website so we can see what the issue is directly in the browser.
