Intermittent 404 pages net::ERR_EMPTY_RESPONSE
Development and Programming
Hi
I have issues on expression engine with 404 (net::ERR_EMPTY_RESPONSE) especially in admin
I am on version 3.2.1
pages work sometimes but at other times they dont and need 4 or 5 refreshed before they load
GET …/system/index.php?S=0&D=cp&C=javascript&M=combo_load&file=cp/global_end&v=1459849577 net::ERR_EMPTY_RESPONSE index.php?/cp/publish/edit&filter_by_channel=1:311 GET http://www.ntrplc.com/system/index.php?S=0&D=cp&C=javascript&M=combo_load&u…obal_start,cp/form_validation,cp/sort_helper,cp/fuzzy_filters&v=1459849584 net::ERR_EMPTY_RESPONSE
i was also getting errors related to chunked data
I have set my php memory to 512mb in my htaceess file
I turned on debugging and i am getting this error
WARNING Cannot modify header information - headers already sent by (output started at /home/ntrplc/public_html/index.php:1) ee/legacy/core/Input.php, line 249
The host guys came back and said that
“I turned on output_buffering in php.ini to 4096 (4MB), it appears you are sending the body before finalising HTTP headers which would be the cause of the issue. Enabling buffering may slightly slow reponses. Please ensure you have no bytes or output before any calls to session_start() (common cause is to call this after sending output) if you have any custom code on EE. Or consult the EE forums.”
Is there an issue with my config or installation?
Thanks
Also not sure if this has any affect on the issue but
I cant set “Use HTTP page headers?” to yes. If always defaults to no after saving
A couple of questions:
- Do you have any third-party add-ons installed for this site?
- Does the 404 only happen with URLs related to getting Javascript?
Hi Seth
No 3rd party addons
This has been happening since i installed the ee. Have installed twice now
I disabled gzip which has helped. I am not getting as many empty response 404 pages
The majority of the time the issues occur in admin cms
Tried testing again just now
Same issues
404 when i try to login.
i tried to enable Use HTTP page headers? but either i get a 404 or it doesnt save
Frustrating.
Front seems fine after gzip disabled but backend has the issues
From my inspecter
