409 Conflict WPForms w/Litespeed and QuicCloud

Hey @blake232,

Thank you for reaching out and sorry for the trouble there!

Could you please confirm if excluding the page from caching fixes the issue for you? I can see from the header that it has a hit on the cache:

HTTP/2 409
content-type: text/html; charset=iso-8859-1
x-qc-cache: hit
date: Wed, 12 Jun 2024 14:42:00 GMT
server: LiteSpeed
x-qc-pop: lej613-hyb-worker.quic.cloud
alt-svc: h3=":443"; ma=2592000, h3-29=":443"; ma=2592000, h3-Q050=":443"; ma=2592000, h3-Q046=":443"; ma=2592000, h3-Q043=":443"; ma=2592000, quic=":443"; ma=2592000; v="43,46"

Thank you!

Thanks for getting back so quickly.

Yes I’ve already added “/contact/” to the “Do Not Cache URIs” list and the error is still present.

There is a “Do Not Cache Query Strings” options also but I do not know what to put there or if that would help.

Hey @kmacharia. Sorry I did not tag you in the previous post so was not sure if you were notified or not.

Hey @blake232

Thank you for getting back to me. It is a bit odd that adding the URI to exclusion list did not work. In most cases, exluding the page works but for some odd reason the page is still getting cached when I check from my end:

content-type: text/html; charset=iso-8859-1
x-qc-cache: hit
date: Thu, 13 Jun 2024 14:02:05 GMT
server: LiteSpeed
x-qc-pop: lej613-hyb-worker.quic.cloud
alt-svc: h3=":443"; ma=2592000, h3-29=":443"; ma=2592000, h3-Q050=":443"; ma=2592000, h3-Q046=":443"; ma=2592000, h3-Q043=":443"; ma=2592000, quic=":443"; ma=2592000; v="43,46"

Could you please share more details about the findings from the LiteSpeed support team so that I can pass along this issue to our development team for closer investigation?

Thank you.

Hey @blake232

Just a quick follow-up, could you please check if you flushed the cache after excluding the page from caching?

Please let me know how this goes!

Hey @kmacharia Sorry for the slow reply I’ve been attempting to troubleshoot. For some reason I ran across a period where the page would not load at when I had it excluded and purged all cache.

The issue is still present after having purged cache and sometimes the page does not load.

Litespeed tech said the following: the redirect loop issue happens on your origin site with Apache, not from QC/LSCWP.
You might want to check if there’s any redirect rule in the .htaccess file, or redirect plugin like an SSL plugin or simple URL plugin ..etc.

When examining the htaccess I did not see a loop but am also not well versed enough to recognize it.

Hey @blake232

I’d recommend checking out the following guide on some tips that you can follow to troubleshoot this issue. The best place to start would be any SEO plugins that help to modify the .htaccess file. I would also recommend checking the issue can be reproduced when you only have WPForms activated. You can try using the steps in WPBeginner’s detailed guide on troubleshooting WordPress to see if it helps resolve the issue?

Please let me know how this goes!

Hey @kmacharia,

I ran through the plugin elimination process and the conflict seems to be with WPforms and Really Simple SSL which using Litespeed.

The error is not present if I remove wpforms or Really Simple SSL. Apparently the redirect loop is caused by Really Simple SSL but only triggers when WPforms is also on the page.

I’ll reach out to really simple SSL and update the chat if the issue is resolved but for now am going to disable really simple SSL because when the three plugins are utilized on the same page it causes a redirect loop 409 error. Hopefully this helps some others also.

Hi Blake,

Thank you for sharing your findings. Please keep is posted. In the meantime, I will also run some tests on my end and share my findings with our team!

Thank you!
