I updated EE from 2.2.2 to 2.7 core and moved the site to a subdomain called ee.mydomain.com. I changed the URL in config.php and in Admin/General Configuration, and admin works fine.
But when I try to view a page in the template editor or the site as a whole, all I get is the error
"Unable to load requested field type file: ft.wygwam.php.
Confirm the fieldtype file is located in the expressionengine/third_party/ directory"
I'm not using the Wygwam add-on and never have. The system/expressionengine/third_party folder is empty except for an index.html file.
Setting the debug flag in main site index.php shows no errors.
If it matters, I have this in .htaccess, but it makes no difference with it or without it when viewing the site:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond $1 !\.(gif|jpe?g|png)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>
Any ideas? How can I delete references to the ft.wygwam.php file? Are they in the database?
