 * Since updating WP, I’ve got this error message on my main page:
 * () expects parameter 1 to be a valid callback, class ‘collapsArch’ does not have
   a method ‘enqueue_scripts’ in /home/customer/www/kellijaebaeli.com/public_html/
   wp-includes/class-wp-hook.php on line 307
 * I do the work of about 10 people, and I have precious little time to become an
   expert in this area…I have no idea what to do to get rid of this error. I wish
   there was some kind of automated fix. ANy idea how I fix it?
    Thanks in advance
   for any help or insight.

 * The error message is generated by the Collapse Archives plugin. In the support
   forum for this plugin, others have already reported the problem: [https://wordpress.org/support/topic/update-caused-the-problem-it-meant-to-fix/](https://wordpress.org/support/topic/update-caused-the-problem-it-meant-to-fix/)–
   my advice would be to also contact the developer in their support forum.

 * Thanks so much, threadi. I went to that link and they suggested using the rollback
   plugin. I was unaware of this, but got it, used it, and voila! the error message
   at the top of my landing page disappeared!
    I’m always shocked when solutions
   are easy–shocked, but not complaining, mind you. Thanks, have a good day.
