    Hello,

    I searched the forums and the internet looking for a solution but couldn't really come up with anything. I'm running CentOS 7.3.1611 and when I run yum info libpng, I see I have libpng-1.5.13-7.el7_2:
    Code:
    root@franklin:[/]# yum info libpng
    ...
    Arch      : x86_64
    Epoch    : 2
    Version  : 1.5.13
    Release : 7.el7_2
    ...
    
    I'm also running cPanel v11.60.0.28.

    Whenever /usr/local/cpanel/scripts/upcp --cron gets ran, I see 42 of these warnings:
    Code:
    [2016-12-30 04:27:53 -0500]    - Processing command `/usr/local/cpanel/bin/sprite_generator`

    I'd like to know how to fix it so I don't see these messages anymore. They're a bit annoying but don't seem to affect the system at all. My understanding was one cause could be from an outdated version of libpng, but from my research, I believe libpng-1.5.13-7.el7_2 shouldn't be affected by the bug.

    Any ideas what's going on and how to fix this? These warnings weren't always here. I want to say they showed up maybe a couple months back?

    Thanks!

    Well, it's been a few days since I've posted and I haven't gotten any responses.

    Does anyone else experience the same issue? Anyone who runs CentOS 7? I'd like to see if it's something with my system or if it's something with all CentOS 7 systems. Thanks!

    Hello,

    I'm unable to reproduce this issue on a test system using CentOS 7.

    Are you able to reproduce the issue when manually running the /usr/local/cpanel/bin/sprite_generator command? If so, please open a support ticket using the link in my signature and we can take a closer look. You can post the ticket number here and we will update this thread with the outcome.

    Thank you.

    Yes, manually running /usr/local/cpanel/bin/sprite_generator produces the commands.

    Can I open a support ticket with cPanel instead of BuycPanel.com? I don't really like their support and prefer to use your support. I don't mind the extra wait time.

    Thanks!

    A small update as well, when I run /usr/local/cpanel/bin/sprite_generator --verbose, I seem to see the message with those dang Attracta image files (like /usr/local/cpanel/base/frontend/paper_lantern/styled/basic/icons/attracta_seoforresellers.png). The Attracta was some free plugin that came with the cPanel license from BuycPanel.com. I don't even use it. Perhaps I should just remove it? I do feel like I shouldn't be seeing this message though, even though the png's are from Attracta.

    Should I still open the ticket? Thanks!

    Hello,

    Could you verify if the issue persists now that the Attracta plugin has been removed, per your other thread?

    Thanks!

    The issue still persists after running their commands. So I run:
    Code:
    root@franklin:[/etc]# cd /
    root@franklin:[/]# find -iname attracta*

    ./var/cpanel/template_compiles/usr/local/cpanel/whostmgr/docroot/templates/software_components/attracta.tmpl
    
    To me, this says they didn't know about the other files that were still left over. These are only attracta files that start with the word attracta. What else might be there from them that doesn't start with attracta I wonder?

    For the /home/virtfs, should I delete those files or just delete the files from the other directories, and then they'll automatically get removed from the /home/virtfs directory?

    Thanks!

    Attracta wanted all the information I could provide. They plan on upgrading their uninstallation script, to make it more EasyApache 4 friendly. I offered to run the generate_sprites --verbose command, and share the output with them. They wanted it so I shared it with them. I believe they don't work on the weekends, so I probably won't hear back from them until Monday or so. Hopefully, their new script will remove the remaining remanence.

    From the sounds of it, they might just not have been aware that their script wasn't properly removing everything. So far, their support has been wonderful. They respond very quick like and even though I'm getting rid of their plugin, they really seem to care and want to help.

    Thanks!

    This problem is now solved, in a kinda unofficial way. Attracta told me to remove the files manually at this time while they continue to work on fixing their uninstallation script. Manually removing the PNG files fixed the interlace warning message.

    Thanks!
