QR code size error on invoice/ticket

Also getting the error message with the invoice template and image (that I copied the html from another reply you gave - I had the same issue of the invoice being blank after install). I've reverted to the older version of tcpdf as you suggested and it is now working.

I tried sorting this by ensuring that the image in the invoice template was given a height and width in it's property settings. After I'd done this I didn't need to revert back to the old version of TCPDF for the invoice to be processed BUT there was no image in the final pdf. I'll do some further testing......

I had to apply this old library today to EB 2.4.1 to fix a "TCPDF ERROR: [Image] Unable to get the size of the image:" error that a customer brought to my attention. The image file was one that was being generated off-site. I will have to look into it further (it happened after using the Pay Offline payment method, which I haven't used in a long time) but at least I have registration running again.
