On overleaf.com, Windows 7 PC, my LaTeX files are compiling with no warnings or errors. The PDF is being created OK also.
I keep getting the following error when I attempt do download as zip:
Sorry, the export failed. Please try again; note that you may have to make a change to your project first. If this problem persists, please contact us.
First tried, searching on-line for the error text. Drew a blank.
Second searched https://tex.stackexchange.com. Drew a blank.
As the compiler is generating neither errors nor warnings and I have successfully downloaded zip-files up to now, I haven't a scooby where to start looking.
