After installing the Constant Contact Forms for WordPress (Version 1.5.2) plugin, we started getting an error in Wordpress whenever we tried editing a post (below). After deactivating the plugin, the problem went away:
Failed to load plugin url: /srv/htdocs/wp-content/plugins/constant-contact-forms/vendor/jtsternberg/shortcode-button/js/shortcode-button.js
More importantly, also when a user attempted to edit a Wordpress Post, a pop-up dialog box appeared in the upper left and stated "No forms available. Visit your forms list to create one." (Screenshot below). Clicking the x to close the window did nothing and users were unable edit the post. This issue also stopped occurring when I deactivated the Constant Contact Forms plugin.
Thank you for reaching out to us! This is an issue we are currently looking into. In the meantime, we suggest deactivating the plugin while you're editing post. We apologize for any inconvenience this experience may be causing and have added you to our queue to be notified when it is resolved.
Thank you so much for your time!
