Hi Pavel,
Thanks very much for the response.
I run all my work through mac with Safari 12.1.1 and on iPad through Safari IOS 12.3.1 , both return the same error. I'd rather not use a different browser as some of the other work I do all runs better on Safari.
See below screen shots as requested. The only thing I can see there is the MBString not being supported (2nd screen shot) by my server. The fact that the PDF Invoice plugin I use functions perfectly, as well as other plugins that generate pdfs I use on different sites on the same serve, to me meant that wasn't the problem.
