HTTP ERROR 500 – When trying to view calendar

  • Having a problem viewing the calendar with everyone’s birthdates showing.

    When I click on the page to view this I just get “HTTP ERROR 500” – This is the page which uses the code “[birthdays template=”calendar”]”

    Any ideas where to start in diagnosing this? – The birthdays plug-in works OK from WP-Admin.

    Thanks in advance

    Any ideas ??

    Also since this post the birthdays widget is only showing the first so many entries and not allowing me to view more.

    The first step for a 500 Error always are the apache/php error logs.
    Please see the logs in order to get ideas where the issue occurs.

    Thanks for your reply.

    Here is what I’m seeing but not entirely certain this is connected to the plug-in ?

    file: /usr/local/apache/logs/error_log

    [Sat Jun 16 10:45:18.213297 2018] [cgi:error] [pid 24094] [client 82.47.246.33:55159] AH01215: PHP Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0: /usr/local/cpanel/cgi-sys/ea-php56, referer: https://www.mywebsite.com/

    This occured at the time I tried to view the public page, but on subsequent visits I am still getting the 500 error, but no new entries into the above log file.

    Any idea where the errors would get logged when accessing the page:
    https://www.mywebsite.com/wp-admin/admin.php?page=birthdays-widget
    This is when it only shows me the first few thousand entries (all on one page) with no option to view the remainder.

    Thanks in advance

    Maybe this is an other issue. Could you try to disable one-by-one your installed plugins in order to find whitch one causes this issue?

    Thanks lion2486.

    Really struggling here.

    I have already tried disabling all plugins but it didn’t help.

    I don’t believe I am using W3TC cache, and have tried increasing the memory limit from 512MB to 8000MB (and returned back) which didn’t have any effect.

    I’ve enabled the debug, but I can’t locate the error.log file it refers to.

    Dear djb2002,

    >>This is when it only shows me the first few thousand entries (all on one page) with no option to view the remainder.

    I would assume there is a JavaScript error breaking the DataTables functionality hence why you receive only some entries. Could you please check your browser’s console log? (You can access it via developer’s tools F12, tab console).

    Hi @sudavar,

    Unfortunately nothing showing there at all. All I get is “JQMIGRATE: Migrate is installed, version 1.4.1”

    I’ve also tried it on another machine and different browser but still the same, although it does show me another 7 rows.

    Any other ideas ?

    Thanks

    If you have enabled WordPress debug log, a file will be created in /wp-content/debug.log according to WordPress documentation

    We are aware that the plugin may not be compatible with the latest WordPress version and there is also a bunch of bugs reported. We intend to re-attend to the plugin, until the next release I can not begin to fathom what the root cause of this maybe.

    Hi,

    I’ll try checking the log files again.

    Yes, I’m running the latest version of WordPress so that is most probably the reason. Hopefully the next update might fix these issues. – I hope so as your plugin has been great.

    Thanks again,
