Our marketing dept just bricked the company website after upgrading the Awesome Surveys plugin. Failure mode is as described above – blank pages (Apache 500 internal error).
From the moment of the upgrade onwards, every page view is failing with the same PHP Fatal error:
PHP Fatal error: Class ‘Awesome_Surveys’ not found in /home/webuser/public_html/wp-content/plugins/awesome-surveys-export-csv/includes/class-csv-export.php on line 3
So it looks like your upgrade does not work with your beta plugin..?
(Marketing have been reminded in strong words that they are not to change plugins on the production server, and *especially* not to do this 5 minutes before home time on a Friday afternoon.)
