Repeating “502 Bad Gateway” after executing simple actions

  • First of all, I’m sorry if that (kind of) issue has already been treated. I looked hard, but I couldn’t really find anything that comes close to my issue. SOme parts of it, maybe, but it doesn’t look like the same issue, all in all.

    I have a number of issues that might have the same source, but I just can’t figure it out. Most probably, my coding knowledge is also not great enough (but pretty basic).

    It all started after trying to install W3 Total Cache. You have no idea how much I regret this. After activating the plugin everything went white screen and the page was gone, including the admin panel. I tried lots of things to get it back (including fiddling around in PHPmyAdmin to really get rid of that nasty W3TC in its entirety), and this sort of worked.

    Everything’s back, site and admin, but from that moment on, certain things just don’t work, and most of the times when they don’t: the server says goodbye and restarts itself, whilst going into 502 Bad Gateway mode, for like 3 to 10 minutes, of course.

    Here are some of the “certain things” I’m talking about:

    – A Google Analytics plugin that displayed stats on the dashboard stopped working completely.
    – Whenever I “send” a command like “delete this or that”, the site gives me a white screen after that. Although, it performs the desired actions.
    – When I want to use the sweet “Add new plugin” feature, I start typing something and the little round thing starts spinning around and never ends. No results at all. Stuck.
    – “Pretty links” don#t work anymore, I mean, the links don’t work. Nothing happens. White.

    I really can’t make out the problem. Here’s what I did, so far:

    – Re-installed wp 4.7, in order to have clean files.
    – Re-installed the same theme, clean files.
    – Uploaded a DB backup from BEFORE this happened. No change.

    The site pretty much “works”, from the outside. Minus the Pretty Links.

    This is it: https://ingovogelmann.netw3tc

    What could this be? I really have no idea, don’t know what to do anymore. Anyone?

    (Sorry for the weird “w3tc” after the URL, that was unintentional)

    Have you had a word with your hosts about this. A 502 error using suggests an issue with the server itself rather than WordPress.

    Sorry, forgot to mention: yes, I did. They said it’s most probably an incompatible plugin. But that’s pretty much impossible as I have the same issues when all plugins are deactivated.

    I wanted to ask the community here first before going further with the hoster. Maybe you guys can come up with something useful.

    @ingovogelmann W3TC usually changes the site’s .htaccess file. I recommend that you:

    * download a copy of this file
    * rename the file to something — .htaccess-w3tc for example
    * save permalinks again from the admin: Settings > Permalinks

    The last step should recreate the file afresh without any W3TC junk in it.

    If that makes things worse, delete the new .htaccess file and rename the old one back to .htaccess

    cheers,

    Did you get this resolved? I’ve had the same thing since 4.7. Deactivated plugins — erratic white screen in the dashboard. Even switched themes to 2017 — same still happened. Sites didn’t have any issues until the 4.7 update.

    Ahh sorry … yes, it got resolved. It was indeed a server issue, a nasty SSL Mutex error. There was a file that re-built itself every time again, now they blocked this function.
