I've installed the Mailchimp extension (v.2.0.1 downloaded directly from https://github.com/veda-consulting/uk.co.vedaconsulting.mailchimp) in CiviCRM v.5.1 (running WordPress 5.2) but the Mailchimp menu items do not get added to the CiviCRM menu. How can I troubleshoot and fix this?
I can manually navigate to the Mailchimp extension configuration pages (such as https://mynonprofit.org/wp-admin/admin.php?page=CiviCRM&q=civicrm%2Fmailchimp%2Fsettings&reset=1). I've also tested and verified that the Mailchimp extension itself is working.
I've also tried manually adding the Mailchimp pages to the Civi menu (via "Administer... Customize Data and Screens... Navigation Menu"). I found that I can add
civicrm/mailchimp/pull to the menu system, but when I add
civicrm/mailchimp/pull&reset=1 to the menu, it results in an invalid menu URL ending in
...&q=civicrm%2Fmailchimp%2Fpull_reset_1. The final
pull_reset_1 part is invalid. Since the
&reset=1 seems to be important for WordPress, omitting it is not a good workaround.
I've tried disabling and reenabling the extension, and completely uninstalling and reinstalling it, but the menu items do not appear. When installing it, the PHP error log file does not log any errors, so I'm puzzled even how to debug this. Suggestions are appreciated.
