    I’ve narrowed it down to this plugin throwing 503 errors on my site. In Debug, I’ve disabled all features and pages work. Re-enable, they don’t. I tried tailing the debug log and it looks like its redirecting infinitely and then crashing? Permissions look correct, the homepage works fine but any internal pages 503. Let me know if there’s any more information I can provide. Thanks!

    Here’s a link to the log: https://gist.github.com/danhere/87653a4ae75ebcff0c4e8087d6645f66

    Environment:
    Ubuntu 18.04
    OpenLiteSpeed 1.4.48
    Wordpress 5.2.2

  • Hi @dsaksa, do you find any server error? Generally, server error_log/stderr.log should provide some hints as to the problem, for more details: https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:php:503-errors

    Hi,

    That’s OpenLiteSpeed issue , instead of plugin issue.

    As the log suggest, you are hitting PHP concurrent connection limit.

    So you will need to go to https://your_server_ip:7080 (you may need to open the 7080 port in firewall first)

    login to webadmin console , if you don’t know login info , you can reset it by following command in server SSH

    /usr/local/lsws/admin/misc/admpass.sh

    Then go to Virtual Hosts —-> your virtual host, (could be named as “WordPress”) —> External App —> lsphp —> and change the following 2 lines to higher number

    If you do not see “external app” in virtual host , then you should go to “server configuration” —> “external app” and change from there.

    After change please restart OLS.

    try change it to 50 or so.

    But be careful don’t set it to high , too many PHP process concurrency might overwhelm your server.

    Best regards,
