Support » Plugin: AGP Font Awesome Collection » Causing a 500 Server Error

  • FYI – This plugin is causing a 500 server error while working in the admin and ONLY for saving changes in the admin, the site otherwise works fine. I suspect this is a plugin vs plugin issue.
    After I reload the error page I return to the admin page and can continue until the next save and then I receive the 500 error again, wash, rinse, repeat….

    Hi ksteele36,

    It is so sadly that you have this issue with my plugin, however I can’t replicate it on several of my development hostings with various configuration and PHP versions.
    Based on this, I guess that it can be server-based issue or some conflict with other plugin.
    Unfortunately, I’m not able to fix this issue without additional technical information from your side. If you want to help with this issue, perhaps you’re able to turn on WordPress debug mode in the wp-config.php – and if you have some errors – pls send it me.
    Also, it will be very helpful if you’re able to create copy of your site on your hosting, clean it from privacy information and give temporary access for me, so I’ll able to see this issue in real time.

    Please let me know, if you are interested to help with debug of this issue here or directly via

    Thank you in advance,

    Sorry Alexey, I have been extremely busy. Thus, my fix was to uninstall this plugin and find another. After I uninstalled my site returned to normal behaviour…. as for tracking the issue down I simply do not have time. Maybe some time in the future if I get a break in projects.

    best regards, “K”

    Oh My God! Why am I? 🙂

    Look at this:

    1) I installed both plugins and really got 500 error
    2) I switched on WordPress Debug Mode and saw the following error:

    Fatal error: Cannot redeclare class Spyc in ../wp-content/plugins/agp-font-awesome-collection/vendor/mustangostang/spyc/Spyc.php on line 68

    3) Both plugins use each his library “mustangostang/spyc” and both trying determinate class “Spyc”. This causes an error.

    The solution for this issue has been described here:

    So, it is unfortunate, that my plugin gets low marks for problems that do not refer to it.

    With kind regards
