404 error using Wakecarter's tool to assign consecutive participant id's

I’m trying to set up my Pavlovia study in Prolific and have implemented counterbalancing based on Wakecarter’s page which assigns consecutive participant numbers and then redirects to alternating URLS.

However when I try to visit the page ‘https://moryscarter.com/vespr/pavlovia.php?folder=EOResearch&experiment=bfi_filler_exp_final’, with or without a slash at the end, I get a 404 not found error. Interesting the url shows participant= 6, but I cannot access the page.

I have also tried with the prolific URL Parameters at the end, e.g ‘&id={{%PROLIFIC_PID%}}’ but that doesn’t change anything.

Any insight would be greatly appreciated!

Hi,

What is the URL for your experiment?

https://run.pavlovia.org/EOResearch/bfi_filler_exp_final/
and
https://run.pavlovia.org/EOResearch/bfi_filler_exp_final/html/

both give 404 errors

which is why my tool is failing to launch them.

Hi, so sorry, I finally realised it’s an issue of an errant capitalisation of the R in research ‘https://moryscarter.com/vespr/pavlovia.php?folder=EOresearch&experiment=bfi_filler_exp_final/’ works just fine now. Thanks so much!
