    Hi,
    I get an error 500 on trying to use the pluginlist in dashboard. Only fix is deactivating the plugin, I have no idea why this happens, sorry.
    Regards,
    Mirko

    You can turn on error reporting: https://codex.wordpress.org/WP_DEBUG

    And then post the error.

    In the apache-log I get:

    mirko [Sat Sep 17 20:31:33 (104)Connection reset by peer: FastCGI: comm with server “/php-fpm-handler” aborted: read failed, referer: https://www.yellowstoneaussies.de/wp-admin/index.php
    mirko [Sat Sep 17 20:31:33 FastCGI: incomplete headers (0 bytes) received from server “/php-fpm-handler”, referer: https://www.yellowstoneaussies.de/wp-admin/index.php

    I tried disabling the Zend opcache. But now I’m quite clueless… the php.ini settings are quite common I think:

    memory_limit = 300M
    max_input_time = 360
    max_execution_time = 4000
    output_buffering = 16384
    post_max_size = 96M
    upload_max_filesize = 64M

    (I tried without output_buffering).

    FYI no helpful information in wordpress debug.log…

    How about the PHP error logs?

    Also, what happens when you turn on WP_DEBUG?

    I’m sorry, there is no information, which would be helpfull, only logging messages from other things… and of course:

    (Sorry for the “Durcheinander”/garbage – this is a copy from a multitail history… which works “quite fine” with ncurses and tmux >.< ).

    And similar errors – the cause of the 500 I think.

    FYI WP Redis works. They say I should delete all transient options, I did (and tried redis cache after that). Everything works but the plugin list I think.

    PHP Memory limit is 300MB.

    Mhh, that sadly not saying anything. Could you ask your hosting provider to have a look at the error and what’s causing it?

    Alternatively, you could try and flush/delete the entire Redis database and see if that fixes it.

    @miwalter try activating the plugin via wp-cli, if that works it suggests a misconfiguration with nginx or php-fpm
