    Hi

    I have plugin installed and configure. I have sing up form on:
    https://hotelkrilo.com/pozdrav-litu-2018/
    Thank you page on:
    https://hotelkrilo.com/pozdrav-litu-2018/thank-you/
    List of participants on:
    https://hotelkrilo.com/pozdrav-litu-2018/registrirani-sudionici/
    And single participant page on:
    https://hotelkrilo.com/pozdrav-litu-2018/sudionik/

    But on sumbiting the sign up form i get blank page and then when i try to refresh sign up page i get 500 Internal Server Error. Same result in any other browser.
    The entry is recorded in database, since its listed in list of the participants page, where click on name shows single particpants page. But i blank page instead of thank you page and on refresh of the sign up page i then get 500 Internal Server Error. And after several minutes i can get page to open.

    Maybe it’s the server issue since i am using this plugin with the same theme and plugins but on the another server and there everything is working fine.

    I tried to disable the plugins but it’s not plugins conflict.

    I enabled debugging in plugin.

    Thank you for any information.
    Best regards

    The reason for your server error may not show up in the plugin’s debugging log, you should look at your server’s php error log to see what is causing the server error.

    500 errors are usually caused by bad code, so if you’re using a custom template, make sure there are no errors in the template. Also, it can be caused by not having a compatible php version. Your php must be 5.6 or later.

    Also, make sure you don’t have any kind of caching active, at least for testing. In general, you shouldn’t use page caching on pages with Participants Database forms, especially if a form will be used multiple times on the same device.

    Hi

    I get this error in log:

    PHP Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 36864 bytes) in /home/admbas13/public_html/wp-content/plugins/participants-database/classes/PDb_Session.class.php on line 344

    I have this variables in php.ini

    max_execution_time = 120
    max_input_time = 120
    max_input_vars = 10000
    memory_limit = 256M

    Best regards

    out of memory errors are very difficult to diagnose, largely because the action that causes the error is often not the one that is causing the real problem. It may be Participants Database, but nothing here helps us know what’s causing the problem.

    Did you try changing the “Use php Sessions” setting in the plugin settings under the advanced tab?

    Yes i did. And I still get the blank thank you page. But it’s ok, it’s not important site, on another server, i have plugin working perfectly on my server and my website, so i will use standard contact form. Thank you very much for your time. Best regards
