    I am using Ninja Forms v3.1.8

    I am now getting an error on my form when a user submits. It was working for a month or so.

    Here is the error (I did remove sensitive data with # and websitename):

    The server encountered an error during processing.
 Uncaught Error: Class 'NF_ESO_Parser' not found in /homepages/14/######/htdocs/clickandbuilds/websitename/wp-content/plugins/ninja-forms/includes/Libraries/EOS/Parser.php:151

    I don’t really know much PHP so I could really use some help!
    Thanks.

    I also encountered the above error.

    Issue is in EOS\Parser.php line 151

    throw new Exception("No Equation given", NF_ESO_Parser::E_NO_EQ);

    Should be

    throw new Exception("No Equation given", NF_EOS_Parser::E_NO_EQ);

    We will be pushing out a fix for this later today, but in the meantime this likely means that you have a calculation on your form that is empty. You can resolve the problem by going to “Advanced” in the form builder, then to “Calculations” and deleting the empty calculation.
