504 Gateway time out?

I’m getting a 504 gateway error shortly after install. I’m able to place the shortcode and get a code generated but if I attempt to change the size of it I get timed out.

I’ve uninstalled and reinstalled and thought I’d leave it alone and then I tried to access ‘Admin Column’ to see if I could display the code on the products listings page and I got the 504 error by accessing that plugin.

Really need to find a QR Code generator, I sure hope this can be resolved soon and not have too many issues in the future.

I also noticed that if I placed the shortcode in the excerpt or content it rendered twice. But, if I placed it by a Woocommerce hook it rendered only one image.

Last thing…

This code is a bit confusing to me… I tried

[wc_qr_code id='{put product_id}’ title='{put QR Code heading}’][/wc_qr_code]
[wc_qr_code id='{put product_id}’ title='{QR Code heading}’][/wc_qr_code]
[wc_qr_code id='{put product_id}’][/wc_qr_code]

[wc_qr_code id='{put product_id}’ title='{what's this? > put QR Code heading}’]
[/wc_qr_code]
