Hi Guys

Seem to be having issues with 400 errors from members since we did the upgrade from 4.6 to 4.7. this is across multiple communities. Not everyone gets the error but when they do they cannot load up the forum unless they log in via incognito or new browser profile. As i said before, it has only been happening since the upgrade. there have been no other changes made to cause the error.

 

Are these all on the same server? A 400 error would be the server stating it cannot process the request for some reason. Are you seeing anything in your server error logs?

Yes this is on the same server. I had a mod who had the same issue and managed to clear it but now and again he gets the same error. I will ask him to note a time when it happens so i can trace the error log.

in the meantime i have attached  screenshot of the error page which states header field exceeds server limit, do you think i need to alter server limits in the httpd.conf? Would this be an oversized cookie and why would this be oversized?

 

 

This would indicate you need to change the limits there, yes. This however is a server side issue rather than one with your software.

It indicates a header that exceeds the size of the limit on your server
