Cloudflare / LiteSpeed Cache Redirect Loop w/ UTM

yeah , that’s one of the biggest challenges for debug , difficult to reproduce the issue

do you have some kind of pattern of that UTM tag ?

I will try to set up some script to automatically and continuously request such URL and see if can catch it

From all of the UTMs added I see a repeat of % being included

This is my latest redirect UTM link ?ct=t%28HOT%20TOPIC_11.09.22%29&mc_cid=8f4327cbfd&mc_eid=37afb7e1e5

It seems to be happening more and more on my larger websites. Please look into this asap as I have angry clients stating loss of sales

Does not happen in 4.6, only 5 and above. I’d suggest looking into whatever updates have changed with UTMs or redirects

so it’s like from

https://domain.com/ct=t%28HOT%20TOPIC_11.09.22%29&mc_cid=8f4327cbfd&mc_eid=37afb7e1e5

to

https://domain.com/ct=t%28HOT%20TOPIC_11.09.22%29&mc_cid=8f4327cbfd&mc_eid=37afb7e1e5

then

https://domain.com/ct=t%28HOT%20TOPIC_11.09.22%29&mc_cid=8f4327cbfd&mc_eid=37afb7e1e5

then

https://domain.com/ct=t%28HOT%20TOPIC_11.09.22%29&mc_cid=8f4327cbfd&mc_eid=37afb7e1e5

and in loop ?

any plugin is used to receive and interpret it? or just for GA ?

klaviyo, google analytics, hotjar are all plugins that all monitor utm tags..

I also have the same problem, the ulr contains UTM, the category page is accessed and page 2, page 3 …. I get the error

some progress:

another user reported same issue , he was able to capture some dev tool output , in that case , the issue was like his URL contains a string like ?utm=xx/xx , something in his wordpress converted and redirected it to ?utm=xx%2Fxx where / encoded to %2F and LSCWP cached this redirection

still working with him to ascertain why or how it got encoded as on my test it doesn’t happen on default WP , and also exploring with our developers to see what are possible solutions

Can confirm it’s always secondary category pages e.g. Page 2 of X shows redirect errors

I have however caught it on the homepage quite a few times on 5.X

The % is always present in the UTM/URL when the error is caused

please try go to toolbox -> beta test -> click “dev” and upgrade

the v5.9-a9 has added a fix to the loop issue, please give it a try
