Sure, I can list some of the recurring log entries:
[09-May-2026 22:01:03 UTC] PHP Warning: Undefined array key "title" in /public_html/wp-content/plugins/ko-fi-button/class-ko-fi-button-widget.php on line 54 [09-May-2026 22:01:03 UTC] PHP Warning: Undefined array key "text" in /public_html/wp-content/plugins/ko-fi-button/class-ko-fi-button-widget.php on line 55 [09-May-2026 22:01:03 UTC] PHP Warning: Undefined array key "color" in /public_html/wp-content/plugins/ko-fi-button/class-ko-fi-button-widget.php on line 56 [09-May-2026 22:01:03 UTC] PHP Warning: Undefined array key "hyperlink" in /public_html/wp-content/plugins/ko-fi-button/class-ko-fi-button-widget.php on line 57 [09-May-2026 22:01:03 UTC] PHP Warning: Undefined array key "code" in /public_html/wp-content/plugins/ko-fi-button/class-ko-fi-button-widget.php on line 58 [09-May-2026 22:01:03 UTC] PHP Warning: Undefined array key "button_alignment" in /public_html/wp-content/plugins/ko-fi-button/class-ko-fi-button-widget.php on line 59 [09-May-2026 22:01:03 UTC] PHP Warning: Undefined array key "html_title" in /public_html/wp-content/plugins/ko-fi-button/class-ko-fi-button-widget.php on line 60 [09-May-2026 22:01:03 UTC] PHP Warning: Undefined array key "" in /public_html/wp-content/plugins/ko-fi-button/class-ko-fi.php on line 244
Keep in mind that the errors have stopped right now precisely because I rolled back to the previous version. The button on the home page is working normally again, with the correct colors, text, and so on. The problems started when the plugin updated automatically. If you’d like, I can manually update the plugin (I’ve actually disabled automatic updates for now) and see what happens. Or I can retrieve other logs (assuming I know which ones).
That (to disable the option) had already done that in the meantime, because it happened this morning as well, and of course I’m a little tired of always having to go and restore the backup of the two files involved.
That said, I don’t understand then where the comfort lies and – more importantly – what has changed. This behavior is relatively new, I have been using the plugin for many years but only recently has it started to behave this way. I do not understand what has changed.
I’m adding to the thread because, in looking for the cause of this problem that also happens on my blog, I noticed that there are at least a couple of discussions about it.
This is the third week in a row that I have been forced to use the backup (fortunately always available) files to retrieve htaccess and wp-config, which turn out to be completely empty, effectively rendering the website unusable (were it not for Cloudflare’s cached pages, which at least do not present me with 404s). There is no shortage of disk space (so what is reported in this thread cannot happen: https://ww.wp.xz.cn/support/topic/fatal-error-empty-wp-config-php-and-htaccess-files-when-disk-is-full/).
This problem is relatively new, I have been using the plugin for several years and this had never happened in the past. Is there a possible explanation or do we have to give up the option that goes to independently update those two files?
Not exactly the problem described by @phoenixuprising, but it is still something related to the wp-image class. Since installing the latest version of the plugin, this is only a very small part of the PHP error file that keeps getting gigantic because of these warnings.
Same here. I have also already tried forcing a cache update and completely deleting the application (in this case Microsoft Authenticator for Android) without success. However, the same application, referring to the iOS store, is shown correctly.
I also add myself to the request/report because, at this time, the PHP log file is continuing to grow larger and larger. I am pasting just for completeness the messages written in the PHP log file of the server:
[15-May-2024 10:11:05 UTC] 🪲 | Meow Lightbox: Output Buffering was used on a non HTML response. Returning the current buffer.
[15-May-2024 10:11:20 UTC] PHP Warning: Undefined array key "geo_coordinates" in /home/demo/public_html/wp-content/plugins/meow-lightbox/classes/core.php on line 224
I have the exact same problem that – even in my case – is constantly filling up the php_error_log going for disk space unnecessarily.
I try to answer the questions about the need for information:
Screenshots or a screen recording showing the issue in action. If possible, please include relevant links as well. There is no screenshot. The problem is detected by going to look at the PHP-related error log, it gets bigger and bigger and never stops getting bigger (fortunately the log rotate then intervenes to trim, compact and set aside the history unnecessarily overrun by this warning).
Finally, when exactly is that message showing up? What action do you need to do to reproduce the issue? It has been happening since you updated the plugin to the latest version available (February 23, 2024).
I already have 5.0.3 but the galleries seem to be so strange compared to the past. You can take a look at this article yourself where the gallery images are shown with incorrect spacing and not real galleries drawn to take up all the space as usual: https://gioxx.org/2022/11/16/you-suck-at-parking
On a test installation I went back to version 4 of your plugins and they work perfectly.
Ciao @tigroumeow, among my tests I did that too without success. I cleared every HummingBird cache locally and even ordered CloudFlare to give me the live version of the website (developer mode) to check it live, but no luck, I kept having the same problems.
