Not saving canvas

[Danish00786]

When i draw feyman diagram online and try to save then it gives error. Unable to open document “file:///tmp/mozilla_danish0/An Example Diagram-2.pdf”. How to fix it?

Did you ever find a solution? I still can't seem to save it.

Yes I have found it. In my case error was due to some script issues. For example after written e^+ instead of e^{+} my issue resolved. So you must check syntax of labels. Make some suitable changes to remove errors.

Thank you! It turns out that despite the fact that the website displays the latex text correctly, you still need "$" on either side to enter math-mode.
