I really don’t know the problem. This occurs after updating.

Me too, exactly same issue as #hauman..

I just update my all in one fav icon plugin too and had the same warnings, but its a simple fix and just a little mistake in the coding of that file.

Simply head to the file in the warning and change the following lines of code from:

'frontendICO' => _('ICO',AIOFAVICON_TEXTDOMAIN),
        'frontendGIF' => _('GIF',AIOFAVICON_TEXTDOMAIN),
        'frontendPNG' => _('PNG',AIOFAVICON_TEXTDOMAIN),
        'frontendApple' => _('Apple Touch Icon',AIOFAVICON_TEXTDOMAIN)
      );

      //mapping of favicon types to translatable Strings
      $this->aioFaviconBackendMap = array(
        'backendICO' => _('ICO',AIOFAVICON_TEXTDOMAIN),
        'backendGIF' => _('GIF',AIOFAVICON_TEXTDOMAIN),
        'backendPNG' => _('PNG',AIOFAVICON_TEXTDOMAIN),
        'backendApple' => _('Apple Touch Icon',AIOFAVICON_TEXTDOMAIN)

Change to:

'frontendICO' => __('ICO',AIOFAVICON_TEXTDOMAIN),
        'frontendGIF' => __('GIF',AIOFAVICON_TEXTDOMAIN),
        'frontendPNG' => __('PNG',AIOFAVICON_TEXTDOMAIN),
        'frontendApple' => __('Apple Touch Icon',AIOFAVICON_TEXTDOMAIN)
      );

      //mapping of favicon types to translatable Strings
      $this->aioFaviconBackendMap = array(
        'backendICO' => __('ICO',AIOFAVICON_TEXTDOMAIN),
        'backendGIF' => __('GIF',AIOFAVICON_TEXTDOMAIN),
        'backendPNG' => __('PNG',AIOFAVICON_TEXTDOMAIN),
        'backendApple' => __('Apple Touch Icon',AIOFAVICON_TEXTDOMAIN)

All that I have done is added an extra _ to each line, which fixes the problem and will stop displaying the warnings ??

Hi,

I just released 4.2.1 where this is fixed.
Weird, I didn’t have any errormessages on my WordPress installation…

Cheers,
Arne

Yes, 4.2.1 fixed that for me. Thanks, Arne!

I was only seeing those messages on the admin side. The sites were fine.

I was having the same problem, but it is fixed now. ??

Dear Techotronic

Thank you for the fix, it is working perfectly
