Publishing problem: "Exception while exporting site"

UPDATES about RW 7.1.x crash while exporting site before publishing

  • Downgraded to 7.1.0: same problem
  • Upgraded to 7.1.2: same problem
  • When I press the PUBLISH button or RE-PUBLISH ALL FILES, RW always crashes on different random files
  • Same problem on different project and different hostings

Finally I was able to update my sites by CTRL-click to PUBLISH EACH PAGE BY ITSELF with its sub-pages

When I edit a very little number of pages, the PUBLISH button usually works.

It looks like RW crashes when it’s going to export higher volume of items and it always crashes 2-3 seconds after pressing the PUBLISH button.

It’s very frustrating, I hope those info might be helpful.
Thanks!
