Javascript Error in Multisite Admin Tool

  • In any screen where there is a user lookup – specifically in multisite -> Sites -> Add New -> Admin Email field – as you type in, it’s supposed to be an autocomplete/lookup field using jquery.

    I get an jquery error now.

    Uncaught TypeError: Cannot use ‘in’ operator to search for ‘length’ in -1

    The server is isolated internally on our INTRANET and has no access to the outside world to do updates and no updates were done to it.

    I have about 10K users now. Is there some limit?

    Have you checked for a possible theme/plugin conflict by disabling all other plugins and temporarily reverting to the Twenty-Sixteen theme?

    Unfortunately, this is a production environment, so those type of changes aren’t possible. But, everything WAS working. Nothing has changed in the last month – and this just started this week.

    Remember, it is always helpful if you provide details about your server. Sometimes there is a well-known issue with the versions of the LAMP/WAMP bundle you are using.
    Server: Linux/Windows & version
    Apache version
    PHP version and memory limit for WordPress
    SQL database server (i.e. MariaDB, MySQL, MSSQL & version)
    WordPress version.
    jQuery version (Using WordPress installed jQuery or external/optional version)

    Have you enabled WordPress debugging, attempted the lookup, then reviewed the debug log to see if there is a more detailed error message? You might have other surprises in the debug log, like conflicting plugins, that are associated with the error. Just remember to disable debugging before you start digging into the log.

    Have you looked at your web server error log for additional information?

    As for the production environment, you could always clone a copy to a development web server. Then you could test & experiment without causing disruptions.
