Favicon cropped versions causing many 404 errors

    HI,

    I have noticed recently that my firewall (wordfence) in wordpresss is blocking a lot of visitors due to too many page not found error 404.

    After digging with Wordfence support, we have found, that the issue is caused by a problem with images, specifically with favicon.

    See screenshot here
    https://ibb.co/C0yyXQ2

    Specifically the favicon image is called Site-Logo-512px.png.

    My site icon is cropped exactly to the specified resolution of 512x512px.

    SO I tried to delete the image file and upload it again in the theme customizer.
    But here instead of a single upload, the system automatically creates a duplicate to the Site Logo 512px.png file called cropped-Site-Logo-512px.png

    This is creating many duplicates in my media library.

    Every time I try to select the original Site Logo 512px.png file, it automatically creates another duplicate in the media library. So there can be many copies of the same file for no reason
    The worst part is, that when I upload the favicon via the theme customizer, I constantly get a lot of 404 error warnings from customers visiting my website as the system is not presenting them correct cropped versions of the site logo.

    Sometimes i have hundreds of 404s from various visitors who do not get the favicon displayed properly.

    I have also noticed, that when I try to set the favicon via ELEMENTOR site settings, then it somehow starts to work a bit again. But not when I do it via the theme.

    I am running a Shopkeeper theme and all plugins and wordpress is updated to the most recent versions

    As for the troubleshooting I am certain that it is caused by the WordPress itself.

    I have created a staging site to troubleshoot and have disabled all the plugins and have used the standard Woocommerce Storefront theme. The issue is still the same.

    Please provide a solution.
    Thank you.

    Kind regards
    Michal

    I recommend getting in touch with Shopkeeper’s support about this via https://themeforest.net/item/shopkeeper-ecommerce-wp-theme-for-woocommerce/9553045/support – as this is a commercial theme they cannot help you here with it.

    HI.

    please read again. And by the way I already did contact the theme developer as well.

    As I have clearly stated above, this issue persist even if I disable SHOPKEEPER theme and all the plugins, with only the WordPress, Woocommerce and the default Woocommerce Storefront theme active. Same issue happens even if I use other themes.

    Here is also the response from the theme developer>

    Adding favicon is native WordPress functionality and not something our theme handles. It could be permissions with your hosting and folders. Have you tried reaching out to them? (I am trying to do that now)

    Alternatively you can switch theme to Storefront (official WooCommerce theme) and see if the issue persists. If it does it’s a theme issue, if it does happen, it’s not a theme issue.     (already tried, so it is NOT a shopkeeper issue).

    After further checking it seems, that WordPress is creating URLs or references to some cropped versions of the favicon, but not actually creating them. I see that various visitors are getting presented the favicon in different resolutions which triggers 404 error in the logs (while the website still works and is displayed, except the favicon).

    When I have checked the wordpress installation folders via FTP, I have noticed that all these cropped versions of the FAVICON are not present in the storage

    1. First off, do you get any previous backups? If so, you could try to restore your WP install with it. If not, I highly recommend you to back up asap before anything;
    2. Like the WP install and its plugins are all up to date. Enable the debugging mode and post here any error/warning messages you’ve got.

    hi,

    I have tried. In fact we have launched a redesigned shop recently on a new and fresh database with clean install of wordpress. All plugins that were used on the previous shop are used on the new website as well (each was installed cleanly). Only difference between our new shop and the old one was the theme itself.

    However as I have noted previously, we have tried to disable all the plugins and the theme and have activated a default Woocommerce Storefront theme which has shown the same behavior in duplicating all the favicon files when we tried to upload them. So it is unlikely that the new theme is the issue. As the theme developer has already stated, they do not modify the favicon upload in any way and it is a WP core feature.

    WP installation and all the plugins are up to date.

    The debug mode was activated and only some warnings about PHP deprecated parameters are showing (the website on the frontend is working normally). Our hosting has recently been updated to PHP 8.4, so this is likely the cause for these warnings.

    Other plugins are not showing any errors.

    We have already communicated these php warnings to the theme developer who confirmed, that they will update the theme to solve this, but it is still unlikey that it is related to the cropping of the favicon in any way.

    Here are a few examples

    kind reminder

    As I wrote above, I would recommend you to contact the support of your commercial theme. All messages from the log originate from them. Therefore, you cannot get any further help here.

    I really start to think that someone is not trying to read the full message

    This has NOTHING to do with the theme and the errors from the DEBUG log are completely unrelated to the issue I have. And by the way after some recent updates even these errors have dissapeared.

    If favicon setting and 404 errors would be happening only when the theme is active, then it is a theme issue.

    But if favicon upload and 404 errors are happenling literally on every theme I install, then it is not a theme issue and all the theme developers have confirmed, that they do not alter favicon settings and are using the wordpress core functions to create appropriate thumbnails.

    As I have stated several times above, this issue persist even when I set a different theme – WORDPRESS is creating a duplicate file for the site icon even though the site icon is in correct PNG, ICO or JPG format and in the correct resolution of 512x512px NO MATTER THE THEME that is currently active.

    The issue is happening on other staging sites that I have where ALL plugins are deactivated and only the default WORDPRESS WOOCOMMERCE STOREFRONT theme is active. So this is clearly a WORDPRESS issue

    Try check out the PHP, WP, all plugins version against the theme supported versions.
