I just recently upgraded my client's site to WP 3.5.2 and noticed in my plugins list, the following error: Fatal error: Class 'RGMailChimpUpgrade' not found in /home/public_html/wp-content/plugins/gravityformsmailchimp/mailchimp.php on line 186
The odd thing is, everything seems to be working okay function wise for the plugin and the site is behaving as should, however when I click into my plugins list, all the plugins listed after this plugin on the list have disappeared.
Any idea or help?
Thanks.
