Gateway 504 Error when posting a new topic

[evolution88]

Hey guys,

I have a strange error. Each time I try to post a new thread my server does not respond and the 504 Gateway error appears after a few minutes. The thread is not published either. Does anybody have any idea on how to fix that or why that issue appears?

Thanks in advance guys!

What content? It might be relevant.

Also, you have a very old version of PHP, which probably doesn't help matters.

It's just plain text, I tried a few words then a lot but that does not change anything. I contacted my host, maybe he/she can update the php version or something. Anything else? Thank you though for your quick help!

That was it! I installed the akismet anti spam plugin. Once deinstalled it worked fine. Thank you!
