Hi! Thanks for the report. This one is puzzling.
Normally, if that error existed, it should be there for everyone (the PHP version should not affect it). I just had a look at line 693 in that file, and there is not an extra parenthesis there (there is a closing parenthesis, but it is needed). I tried it against PHP 7 too, just to be sure.
Can I ask how you uploaded – did you click update from your WP dashboard or download a zip and upload manually?
I had prepped a change to apply PHP coding standards to this file. I was going to put that in the next release, but just as a safety measure, I will prepare a release with that shortly and deploy. In that file, both myself and PHP coding standards agree there are no issues.
Hopefully that will resolve things for you. If not, I may ask if there any chance you can copy the lines of code around that line in your version of the plugin so I can see them. But we can hold on that until after this release..
That release should go out in the next hour.
