Uncaught Error: Call to undefined function caPhantomJSInstalled()

When trying to open "Manage > Administration > Configuration Check", I get the a white page (=PHP error), and the following in the logfile:

[Fri Oct 30 17:01:40.630999 2020] [php7:warn] [pid 4926] [client] PHP Warning:  preg_match() expects parameter 2 to be string, array given in /var/www/providence/app/helpers/utilityHelpers.php on line 518, referer:

I've updated the code a few days ago to git branch "develop".
Any ideas what might be causing this?

Thank you very much in advance :smile:


  • You have an old plugin in your install. Please delete /var/www/providence/app/lib/Plugins/PDFRenderer/PhantomJS.php. It shouldn't be there. PhantomJS is not longer supported as the maintainers seem to have abandoned the underlying application.

  • Ok. Roger that.
    Thanks for the quick reply!
