    id eigenschap
   van een WPCF7_ContactForm object is niet langer meer beschikbaar. Gebruik in 
   plaats daarvan de methode id(). in /home/keesdnm53/domains/petebogsbigband.nl/

    Thanks and regards, Robert

 * Try switching to the default theme (Twenty Seventeen) and deactivating all other
   plugins.

 * Thank you very much.
    1, switching is no option. Contact form 7 worked perfectly
   with the present theme and I would have to rebuild my site. 2. Deactivating plugins
   is the first thing I do when something does not work anymore
 * For you information: the error message is displayed but the form does what it
   is supposed to do.
 * Kind regards,
    Robert

 * This is a technique commonly used in WordPress to find what is actually causing
   a particular problem.
 * Switch temporarily (nothing will be lost when you switch back) to a WP default
   theme & disable all plugins other than Contact Form 7 to see if the problem goes
   away.
 * If it does you can switch back to your theme & re-activate each plugin one by
   one to see when the problem occurs.

 * I don’t speak Dutch but this looks like your CF7 plugin install may not have 
   updated correctly.
 * Delete the plugin folder at wp-content/plugins/contact-form-7/ using FTP (don’t
   use Delete option on Plugins page as this may erase all CF7 forms) and install
   the plugin again.

 * Hi, I found out that the problemmaker is Contact Form 7 Cost Calculator – Price
   Calculation. Enabling this extension caused the problem to return.
    kind regards,

 * It’s often helpful for others if you can report the problem in the support forum
   for that plugin.
