I built a website with CodeIgniter last year www.example.com, and client wanted Wordpress Blog last week. I built the blog and uploaded to www.example.com/blog
Now when I click any link on wordpress it gives error as below :/
http://www.example.com/blog/category/one-last-category/
An Error Was Encountered
Unable to load your default controller. Please make sure the controller specified in your Routes.php file is valid.
How can I set Codeigniter to ignore Wordpress folder?
Appreciate helps!!!
You'll want to do this with an .htaccess file (assuming your web server supports it.) For example, in the DocumentRoot of my Codeigniter site I have an .htaccess file which contains:
RewriteEngine on
RewriteCond $1 !^(index\.php|static|user_guide|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
This allows me to still access static files and the CI user guide. In your case the RewriteCond would be something like:
RewriteCond $1 !^(index\.php|blog)
