Hi there, 

I have uploaded my study (https://mili2nd.co/ddljb). But I am experiencing a strange problem in that when running it on my laptop (a MacBook) it is running fine, however on a windows PC the instructions pages are displaying text that is not in the code at all ('If you require more information, please contact me at mg403@...), but I previously deleted a while ago in an old version of the file. I changed the file a long time before uploading to the script to the web, and never had the piece of text in question on all 3 instructions pages of the study, so it seems strange for it to be displaying across text and pages where it has never programmed to be. I have tried 2 windows PCs and am experiencing the problem on both, I have also tried it on my iPhone and it is not happening there, but the text is appearing on one page, when it should not be there at all. I have attached screenshots too, to show what I mean, and my script. 

Many thanks in advance, 
Mei

This sounds like the old file or files are still cached locally on the Windows PC. Try clearing the system's temporary files and temporary internet files before running the web experiment again on the Windows machine(s).
