Title: WordPress Admin PHP FastCGI 502 Bad Gateway Errors Last modified: August 22, 2016 --- # WordPress Admin PHP FastCGI 502 Bad Gateway Errors * Resolved [theevent](https://wordpress.org/support/users/theevent/) * (@theevent) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/) * Hello, * I recently switched hosting to Media Temple Grid. Shortly after migrating my website I turn on PHP 5.3.29 FastCGI because I was doing everything I could to speed up my site. I began experiencing 502 Bad Gateways while trying to publish new articles (previewing, and even scheduling articles seems to work ok, but I cannot outright push the publish button or it throws a 502). Images often fail to upload, and even clicking around to different sections of the Admin will produce a 502. The 502s only happen when using the backend. * Because I turned on FastCGI shortly after migrating to the Grid, I did not correlate this problem with the PHP change at first. I thought it was a problem with the migration. I’ve been doing much Googling over the past few weeks trying to fix this and finally found other people who are experiencing the same problem, here: * [https://wordpress.org/support/topic/admin-attempting-redirect-to-https?replies=6](https://wordpress.org/support/topic/admin-attempting-redirect-to-https?replies=6) * The problem described and the server errors are _identical_ to my problem. I thought I’d start a new thread, as the one I linked to is quite old. * I turned off FastCGI a week ago (I switched to 5.3.29 CGI (Stable) — or should I switch it to 5.5.18 CGI (latest)?). I am still experiencing the problem and my site is pretty much unusable at this point because I cannot post new articles. * I really have no idea how to correct this problem at this point and I’m hoping some of you kind people can help to point me in the right direction. * I’m so frustrated at this point, I am not opposed to deleting everything and starting over with a fresh WordPress install and a new database. I have a current backup, but would this route even fix the problem since the problem appears to be with PHP? * I found the following information, but I’m not at all sure how to proceed. * [https://kb.mediatemple.net/questions/35/PHP+Safe+Mode,+Problems,+and+Workarounds#gs](https://kb.mediatemple.net/questions/35/PHP+Safe+Mode,+Problems,+and+Workarounds#gs) * [https://kb.mediatemple.net/questions/137/How+can+I+edit+the+php.ini+file%3F#gs](https://kb.mediatemple.net/questions/137/How+can+I+edit+the+php.ini+file%3F#gs) * [http://www.askapache.com/php/php-htaccess-tips-tricks.html](http://www.askapache.com/php/php-htaccess-tips-tricks.html) * I would REALLY appreciate any input anyone has to offer. * Thanks so much, Laurie Viewing 15 replies - 1 through 15 (of 28 total) 1 [2](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/page/2/?output_format=md&replies=8) [→](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/page/2/?output_format=md&replies=8) * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5556980) * Have you contacted your hosting provider about this yet? 502 is a server-level error, not a WordPress error, and WordPress has no known compatibility issues with PHP 5.3.29 or FastCGI. * Thread Starter [theevent](https://wordpress.org/support/users/theevent/) * (@theevent) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5556984) * I have called them and they told me the server was working properly, so the error must be on my end. I had them look at my logs and because the server error has to do with ‘wpbrute.config’ they had the gall to tell me it was because I was entering my password in wrong! I disagreed, and let’s just say the conversation did not end well. * This was before I found out the error was related to FastCGI. I’ll try giving them a call again tomorrow. I have been less than impressed with Media Temple’s tech support. Maybe now that I’ve pinpointed the error they will be willing to help. * I appreciate you taking the time reply. * Thank you. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5556985) * What is “wpbrute.config” from? That’s not part of standard WordPress, and I suppose it’s possible that is the root of the problem. * Thread Starter [theevent](https://wordpress.org/support/users/theevent/) * (@theevent) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5556988) * Every time a 502 happens, I check my server log for clues and its always the same error * `[Mon Dec 08 13:08:13 2014] [error] [client 216.70.122.75] ModSecurity: Warning.

You have confirmed my suspicion. I always do pretty thorough troubleshooting before I call tech support to ensure it is not an issue on my end, but this one had me stumped. There were a couple of things said by the tech that made me think he was not the person I should have been speaking to, so I will use your advice when I call tomorrow. * This has been stressing me out for weeks. I really appreciate that you took the time to reply and point me in the right direction. * Thank you!! 🙂 * Laurie * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5557002) * You’re welcome! * [fyaconiello](https://wordpress.org/support/users/fyaconiello/) * (@fyaconiello) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5557079) * i’m also having this issue on MT: * [Thu Dec 11 06:25:12 2014] [error] [client 173.167.83.17] ModSecurity: Warning.

They had me change the file permissions several times after concluding that it was a permissions issue. However, their diagnosis of the problem and supposed solution has gotten me no closer to a fix. We just turned on error reporting and logging, so they want me to call back in a few hours after the logs have filled a bit. * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5557089) * Ah, sorry, for someone reason I thought the OP had a different hosting provider. I’m aware that MT often = Media Temple. * Best of luck getting that fixed with them. It’s undoubtedly their own custom mod_security configuration. * Thread Starter [theevent](https://wordpress.org/support/users/theevent/) * (@theevent) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5557092) * Two more calls today and still not resolved… * @fyaconieelo The tech I was working with today has a link to this thread, and I made sure to let them know that you’re having the same issue. Has anything been resolved on your end? * Last time I called they offered to turn off their custom wpbrute.config. But for some reason, today they cannot. * I have a news website and if I can’t post the news, people look elsewhere. I usually get around 30,000 page views a day… so far today 3500!! * fyaconieelo, please keep me updated on your situation and I will do the same. * Thanks! * Moderator [James Huff](https://wordpress.org/support/users/macmanx/) * (@macmanx) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5557093) * Hm, I do hope they can fix it. As the error clearly states, the problem is with their mod_security configuration. * Not to stir the pot too much, but if your site is critical, and they aren’t able help with their own mod_security configuration (going on 3 days now), [https://codex.wordpress.org/Moving_WordPress](https://codex.wordpress.org/Moving_WordPress) and [https://wordpress.org/hosting/](https://wordpress.org/hosting/) may come in handy. * [fyaconiello](https://wordpress.org/support/users/fyaconiello/) * (@fyaconiello) * [11 years, 5 months ago](https://wordpress.org/support/topic/wordpress-admin-php-fastcgi-502-bad-gateway-errors/#post-5557096) * my response to them: * > This issue was addressed on the phone call, but never resolved.
