Timeout Trying To Create Qr Codes

Hi Tim, 

Trying to create a QR gallery for the first time - I have a CSV with 220 subjects but keep getting a 504 Gateway Time-Out. 

My site was down today and was told it was due to running Sytist 5.4.2, and as such "your Sytist was constantly hitting the maximum server resources limits for your hosting account."

This was then fixed and upgraded ( I hadn't upgraded as I didn't want to upset my apple cart in such a busy end season )

I was able to print out the 211 QR codes in your QR gallery by clicking the Print QR Codes with subject data button without issue. How to replicate?

Hmm - I wonder how you saw them there? - I just deleted those 211 and tried to upload them again and got a white page with 504 Gateway Time-Out ( nginx/1.27.4 )at the top.. 

But after a bit I I tabbed back to that gallery and there they all were again?
Deleted, refreshed, reuploaded, Timeout, and eventually they are there again ?

Odd?
